Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

b

1l1e stress-relieving process applied to the toneam) fUltller inhibits a successful anodising treatment by interfering with the electron flow necessary for a hjgh-quality clear anodised finish

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Tonearm Geometry This toneanTI utilises a geometry and mounting system compatible with the well-known SME toneanTIs Specifications are as follows

Fuhe Information

The turntable is heavy because it is constructed almost exclusively from Austenitic (noll-magnetic) Stailliess Steel Please do 1I0t drop any pans of the turntable on your foot shysllch carelessness is unlikely to damage the tumtable but will do serious damage to your foot

Dont try and lift the turntable in its fully-assembled state Always remove the platter first - take care of your backbone

Dont try and lift the turntable by gripping the arm board Lift using the module Jim only - tlte armboard will be damaged otherwise

Bew3e of the free-standing nature of the motor unit If the motor falls pulley-side down the drive ullit will have to be replaced If the transfer bealing falls sufficient damage will be done to require total (and expensive) replacement So be careful please You have been wanted

If the turntable runs slow the problem will almost certainly be of a mechanical rather than electlical natllre Ellsure that the tumtabJe and tnmsfer beaJings spin fieely (clean thoroughly and add fresh oil ifnot) and that the drive cords ltlre cOlTectly locltlted tensioned and free of oil contltll11il1~tion (clean them with a mild household detergent if soiled)

If the turntable runs fast the most likely cause will be incolTect alignment of the dlive cords (not running in the pulley grooves but on a surrounding lim) simply re-align the offending drive cord (typically 011 the transfer beltllil1g rotor)

Tensioning of the drive cords will be arrived at by feel once you iJave the initial set-up pelf0l111ed ll1e accompanying diagram indicates a useful starting point The basic objective is to establish a tension which generates sufficient torque with minimum start-up time However if the tension is too grent there will be insufficient slip for the motor to initially spin and synchronise If there is too little tension the dlive cords will vibrate excessively and tUI1Jtltlble staJt-up time will be velY slow

When using the 78rpm pulley it will be necessalY to give the platter a helping hand fiom stlIIdstill - once the dlive hltls synchronised there vill be sufficient torque to attain and lmintain coonect speed It is beneficial to give the platter lt1 push stan in all circumstances shydlve cord life will be extended ltlnd motor stress reduced

Placing of the turntable unit should be carefully considered ll1is tUnltable will give excellent results in almost aJl circumstances but when placed Oil all tmly solid base evell better results can be obtained A 30mm thickness slate baseplate (size 580 x 358mm) is typically supplied with the unit for this pUIl)Ose This should be mounted on a dedicnted support table or wall-mounted plltltfonll

Do not nllow the armboani to become w(t at any time 111e almboard should only be dusled with a dry cloth and perhaps a little y polish

It

Drive cords TIle platter drive cord is a olle-piece moulding of neoprene rubber The specification is ID360 x 16mm section (thickness) TIle flashing residual left over fiom the mouldillg process has been kept to a minimum but is to some degree an inevitable consequence of the manufactUling process As the cord lides in a V groove (rather than a semicircular groove) the flashing will not make actual contact vith either the pulley or platter groove and thus is not of mechanica I impOItance

Whilst it is always preferable to replace a W0111 drive cord witb a new one an effective repair to a broken cord can be made as follows square off the broken ends of the dtive cord and bond together witb a small drop a cyano-acrylate adbesive (super-glue) Tills bond will effect a temporary repair to keep the turntable operational until a new replacement cord can be obtained The butt joint just desctibed is simple effective and fast A better joint is the scalf joint this involves splicing the two ends of the cord at an angle of approximately 45 degrees The scarf joint is a more reliable joillt and offers greater longevity but is more difficult to make and dislikes bending around small diameters

1pound it is not possible to obtain an original dlive cord a workable dlive cord can be made by purchasing a one metre length of I 6mm (or 1 16) lleoprene o-ling cord and splicing it into a ring as described above

nle transfer beclling dJive cord is made of a similar (though more ligid) polymer to a nominal specification of ID 35 x 1116 section (for 60Hz units lD325 x 1116) An emergency cord can be fabJicated by the method desctibed above though in this case tbe lengtb of cord prior to bonding should be 280mm (for 60Hz 260mm)

Please note that whilst the exact intelllal diameter of the dlive cords is not so clitical the cross-section (or thickness) of the cord is impoltant A thicker section of cord will cause the tUllltable to run fast and a thinner section will l11(lke the tllllltable run slow - so stick to the 116 section cord speci fied

ll1e drive cords will stretch with age but the free-standing nature of the motor dlive system means that dlive cord life can be extended simply by moving tbe motor andor transfer bealing assel1lbly filltber from the platter andor each other (llle platter dlive cord can be heated in an oven ill 130 degrees C for 30 minutes to bJing about some sllJinkage of the intemal diameter if overly stretched though this is not recommended unless you enjoy food which tastes ofmbber - it is more sensible to simply replace the drive cord witb a new one)

E~l)OSme to ultraviolet light and ozone will shorten the life of the dlive cord polymer (along vith old age) so dont expose the tumtable to either if you can help it Multiple spare drive cords (lre Jlot included with the equipment because of the natural ageing process - it is best to purch(lse replacement dIive cords when necessary (from a fresh polymer batch)

Oil It is essenti(l] to keep the bearing assemblies fully flooded with clean oil ill all times A high qll ~i1 ity clear (lnd nOIl-viscOliS oil is optimulll - (IS supplied Dont use tllick viscous and exotic nils 1lllder nny circllInstnnces these might nttnck the bealing bush linillgs and cause all man I of difficulties Keep it simple l

LiftLower Mechanism To raise the toneallD the cueing lever should be lifted upward into the veltical position To lower the stylus onto a disc the cueing lever should be depressed fOlward and downward wltil the lever is hOlizontal When raised the stylus should rest about 5-8mlll above the disc sUlface - adjustment can be made by looselling off the small set screw in the cueing beam body and raising or lowering the lifting beam or the entire cueing mechanism may be raised or lowered by adjusting the height of the whole cuelbias platfonD It is not necessalY to add oil or any other lublicant to the cueing mechanism - this has already been done The mechanism should require no maintenance at any time though the ntbber lip on the cueing beam may be wiped with a mild detergent solution to restore its tack if contaminated by oil or dust

Gias Assembly The purpose of an anti-skating force is to counteract the natural tendency for the toneanD to swing inwards and over the centre spindle 111is action is attlibutable to the overhanging nature of the stylus and is an unavoidable aspect of any pivoted toneann The bias assembly applies a counteracting force It should be noted that the skating tendency of the toneanD is 1I0t constant across the whole disc surface It is best to initially set the anti-skating force for optimum response nearest the inner groove radii Later eq)elimel1tatioll will confirm whether or not this initial setting will need to be revised Bias adjustments can only be set dynamicalJy whilst the toneaml is tracing a record Using tbe ear to detect tracing distoltion is probably the only truly satisfactolY method of setting the bias force conectly Should tbe bias wheel stick a small drop of lublicating oil 011 the wheeJ journal should help

Tonearm Viring The tonealID tube is wired with four strands of silver-plated copper wire sheathed in a ptfe (Teflon) coating This choice of wire was made with due consideration to both sound quality and flexibility A nnipivot toneann by its nature prElhibits the toneann wire from exiting through the beating centre - cable flexibility is thus an impoltant issue as an inflexible wire will impede free movement of the toneanD VelY small gauge wiring may be more flexible though often at the expense of sOllic constliction and mechanical fragility 111e chosen wire has a powerfitl and clean sonic signature and providing care is taken to ensure thJt its routing to the connector assembly does not impede toneanTI movement win provide both good sound Clllality and mechclllical integlity (very fine wires are easily broken involving illtricClte re-soldering operations of a initating nature) As the toneann tube is sealed at botu encls and intcntcdly damped rewiling of the tube will not be possible Please therefore take

l Ie not to break any of the wires

Surface Finish All the slll-faces of the tOlleanD have been stress-relieved and satin-finished lite aluminium palts are NOT anodised because the anodising process forms a thjn but very h~ld byer of aluminium oxide 011 the metCl]s skin Whilst this anodic film helps protect the b l ~ emctal from COITOSiOIl and scratches it also creates a hard edge to the sound of the tOIlClIm For me this is an unacceptable compromise J have therefore chosen to protect the met)1 vith a film of soft wax (CI natural anodic skin wi I develop in time anyway) Jeaving the lco llstic properties of the toneanTI Ilncompromised ifnot improved

FUlthcnllorc anodising can only be successfully employed where the basemetal is Cl Ij ~ h-Plllty fllUll1illillll1 - such flluJ11iniull1 j nlso very soft mel therefore structurally ill-suited to uc ill an npplicntioll such as this Allo ing of the (lIUllliniulll with other metals to create a h i ~ h-strcllgtlt lJ1lt1terial therefore often preclud es the possibility of later sllccessfit surface ll l() dj~ing

For these reasons special care should be taken whilst handling the tonearm not to scratch the delicate surfaces

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Output Cable T11e Output Cable carries the very small signals from the tonealID to the phono amplifier This cable should be of a larger gauge than the internal toneann wiring The connector bracket is typically fitted with two high-quality insulated RCA phono sockets (fully balanced connectors may be supplied to order) pennitting a standard phono-to-phono cable set to be used ntis anangement allows expelimentation with different cable sets to be made with ease Please note that although the RCA pllono C0I111ectof is essentially an unbalanced connector the insulated configuration of the connector plate socketry permits a quasi-balanced mode of operation without the need for complex (and expensive) non-standard balanced cable sets As some systems (and listeners) ilfe more cable-sensitive than others final choice should always rest with the individual user An ealtlung drain wire mayor may not require to be run from the phono amplifier ground tenninal to the ground telminal on the toneanu COlUlector plate - this will depend entirely upon the overall earthing anangement of the individual system A drain wire connected in this way will effectively earth tbe entire tonearm assembly and may also be routed to the tUllltable module body to ealth the entire tUllltable assembly too

Tonearm Geometry This toneanTI utilises a geometry and mounting system compatible with the well-known SME toneanTIs Specifications are as follows
