HIGH VOLTAGE WARNING

Operation of this receiver, outside its cabinet or with covers removed, involves a shock hazard from the power supplies. No work should be attempted on this receiver by• anyone not thoroughly familiar with the precautions necessary when working on high voltage equipment.-

CATHODE RAY PICTURE TUBE H.ANDLING PRECAUTIONS

Extreme care must be used in handling the picture tube. This tube is highly evacuated and, d u p to its large size, is subjected to a considerable atmospheric pressure. The handler should wear safety goggles and gloves for protection. Avoid nicking or scratching the glass by rough contact with other objects.

Before removing glass tubes, discharge the capacitor formed by the inner and outer aquadag coatings on the tube by shorting the anode contact on the side of the tube to the outer surface with a well insulated piece of wire,

INSTALLATION AND OPERATING INSTRUCTIONS

RECEIVER LOCATION

The receiver may be placed anywhere in the room, but for greatest satisfaction it should be located:

l. Away from any bright light that may fall directly on the screen or be reflected from it; this includes windows and lamps. Some illumination in the room, off to one side, is desirable, however, to prevent eyestrain.

l. To provide comfortable viewing and ease of operation.

3. At lease one -inch away from a wall to allow for cabinet ventilation. This is very important.

ANTENNAS

The choice of a television antenna depends entirely on the location of the receiver with respect to all television station transmitting antennas in the area. Maximum pickup is obtained when the receiving antenna is directly in line of sight with the transmitting antenna.

"Bilt-In-Tenna." All receivers using the TS-ll4 series television chassis are equipped with the Motorola "Bilt-InTenna", mounted inside the cabinet, for use in good signal areas.

When this antenna is used, the following precautions should be observed for best reception:

l. In order to get maximum performance and satisfactory pictures from the "Bilt-In-Tenna", ample signals from the television station must be present at the location of the receiver. Normally, the strength of the signals will vary throughout the room in which the receiver is located. For this reason, better pictures will be obtained if the receiver is tried in all possible locations in the viewing room and is then placed where the clearest pictures are received from all stations. Avoid large metallic objects, such as radiators, metal panels, etc.

l. Lamps, vases and metallic objects, when placed on top of the receiver, may affect the ~fficiency of the "Bilt-In-Tenna".

Indoor Antenna. If additional pick-up is necessary an indoor antenna, placed on or near the receiver, maybe used. The antenna should be rotated and the arms should be adjusted for the best signal, with no ghosts or reflections. Normally, the arms should be extended on the low channels (Z-6) and telescoped on the high channels (7-13).

Outdoor Antenna. The Motorola "Bilt-In-Tenna" or the indoor type antenna will give satisfactory reception in strong signal areas; but, if the receiver is located in a fringe or weak signal area, an outdoor antenna is recommended.

In areas free of obstructions and reflections, within reasonable proximity to television transmitters, a dipole and reflector will prove satisfactory. Since such an antenna has a relatively small band coverage, a special antenna covering all twelve television channels should be used if it is desired to receive stations on channels of widely separated frequencies.

I-:ocation of the antenna should be decided from the stand-

point of maximum signal pick-up. ln general, the antenna should be broadside to the tFansmitting antenna and should be as high as pas sible. If a reflector is used, the antenna should be oriented so that the driven element is closest to the station and the reflector farthest away.

Locating the antenna and lead-in as far away as possible from highways, hospitals, doctors' offices, electrical machinery, etc., will help to reduce noise pick-up from such sources. Also, it is desirable to keep the antenna at least six feet away from other antennas, metal roofs, gutters, or other metal objects to prevent unwanted reflections and shielding.

Lead-In. Since the TS-ll4 chassis i~ designed for 300 ohm input, the standard 300 ohm twin lead line should be used for connecting the outside antenna to the receiver. Twisting the line one complete turn per foot of running iength helps to reduce noise pick-up on the line. The lea.d-in should be supported on stand-off insulators and kept tight enough to prevent mechanical damage through swaying. Avoid running the lead-in close to metal gutters, iron standpipes, etc.

In areas of very strong signals, or where severe local electrical interference is encountered, 300 ohm shielded twin lead is recommended. The shield braid should be grounded.

An approved lightning arrestor should be used.

RECEIVER ANTF:NNA CONNECTION

The antenna lead-in to the receiver is connected to the two screws of the terminal strip on the rear of the cabinet. Disconnect the "Bilt-In-Tenna" leads from the terminal strip before attaching an external antenna lead-in. Sometimes, reversing the lead-in connections at the receiver may improve picture quality and overall performance.

OPERATING CONTROLS

There are two dual controls, consisting of a small and a large knob each, on the front panel of the receiver. The function of each control is marked on the front panel, the "circle" indicating the large knob, and the "dot" indicating the small knob. See Figure l for front panel control functions.

SERVICE ADJUSTMENT CONTROLS

The receiver is completely adjusted at the factory, so normally none other than the front panel control operating instructions need be followed in putting the receiver in operation. However, to provide for any misadjustment of the service controls, due to handling, the following instructions are in order. See Figure 2 for location of the service adjustment controls.

FOCUS CONTROL

The FOCUS control should be adjusted until the fine horizontal line structure of the raster is clearly visible over the picture area. The control should be tuned through the correct point several times so that optimum focus is obtained.

CENTERING

By means of a lever extending from the focus coil, thru the rear screen, the focus coil can be shifted to center the picture in its mask.

VERTICAL SIZE AND VERTICAL LINEARITY

Adjust the VERTICAL SIZE control until the picture fills themaskvertically. Adjust the VERTICAL LINEARITY control for best overall vertical linearity. Adjustment of the VERTICAL SIZE control will require a readjustment of the VERTICAL LINEARITY control and possibly of the vertical hold control. Center picture with the centering lever on the focus coil.

HORIZONTAL SIZE

Adjust the HORIZONTAL SIZE lever until the picture fills the mask horizontally. Center picture with the centering lever.

HORIZONTAL HOLD ADJUSTMENT

The HORIZONTAL HOLD control should have a sync range of approximately 180°. If the control is too critical, adjust as follows:

l. Short out HORIZONTAL OSCILLATOR coil L-23. This may be done with the chassis in the cabinet by shorting pins 3 and 8 of the test socket on chassis rear.

2. With the centering lever, move the picture to the left so thatthe rightedge of the raster can be seen. Adjust the HORIZONTAL HOLD control to about the middle of its range and note the width of the blanking pulse. (The blanking pulse appears as a gray bar at the right edge of the picture).

3. Remove short from HORIZONTAL OSCILLATOR coil.

4. Adjust HORIZONTAL OSCILLATOR coil until the same amount of blanking pulse can be seen as was noted in step 2.

VERTICAL HOLD ADJUSTMENT

Adjust the VERTICAL HOLD control for the center of the vertical sync lock-in range.

BRIGHTNESS

Adjust the BRIGHTNESS control, in combination with the CONTRAST control for the most pleasing picture. Keep the brilliance slightly below maximum, however, in order to protect the fluoresc-ent screen of the picture tube and to prevent poor picture detail.

the ion trap to become misaligned. To prevent serious damage to the picture tube, the following method of adjustment should be used. See Figure 3.

The magnet should be placed on the neck of the tube in the direction indicated by the marking on the magnet (usually an arrow which points toward the picture tube screen} so that the stronger magnet of the double magnet type or the only magnet in the single magnet type, is positioned over the internal pole pieces which are mounted on the gun structure. Adjust the brightness control for low intensity and move the magnet a short distance forward and backward at the same time rotating it to obtain the brightest raster. If, in obtaining the brightest raster, the ion trap magnet has to be moved more than l/4" from the gun pole pieces, the magnet is probably weak and a new magnet should be tried. Never correct for a shadowed raster with the ion trap magnet if such correction results in decreased brightness. The ion trap magnet must a lways be adjusted for maximum brightness and, if shadows occur at this setting, they should be eliminated by adjusting the focus and deflection coils as explained under "Focus Coil and Deflection Yoke Adjustment".

CAUTION: Keep brightness control at low intensity until ion trap is properly set.

A mirrorpl,aced infront of the receiver will aid in making this adjustment.

DEFLECTION YOKE ADJUSTMENT

If the deflection yoke shifts, the picture will be tilted. To correct, loosen the thumbscrew on top of the deflection yoke and rotate yoke until the picture is straight. Before tightening the thumbscrew, make certain that the deflection yoke is as far forward as possible.

If the yoke support and the picture tube have shifted in transit or, if for any reason, these parts have been removed and replaced, it is best to do a complete job of repositioning.

See 'Figure 3. The starting point is the position of the picture tube. It should be adjusted so that the distance from the center of the tube face to the front edge of the chassis is l ". The clamp on the front of the tube should then be tightened. The picture tube rear support bracket positioning adjustment screws should be loose enough to permit sliding the bracket forward until the rubber cushion fits snugly up against the flare of the tube. Loosen the yoke adjustment thumbscrew and push the yoke up against the flare of the tube . CAUTION: Do not use force in sliding the bracket up. If too much force is used, a strain will be placed on the neck of the tube when the support bracket positioning adjustment screws are tightened. Also, the yoke may be forced out of position. The opening in the yoke should be concentric with the neck of the tube.

FOCUS COIL ADJUSTMENT

The focus coil should be positioned so that it is spaced l/4" from the deflection yoke when parallel with the yoke. The opening in the yoke should be concentric with the neck of the tube . The spacing should be adjusted before the front of the picture tube is clamped down, because it is ne cessary to remove the tube to change the position of the focus coil. Its position is changed by choice of location of the coil mounting studs in the scalloped holes on the top and bottom of the coil mounting bracket. The opening in the coil can be made concentric with the neck of the tube by loosening the nuts on the studs which support the focus coil bracket and turning the studs with a screwdriver in the slots provided. The studs are eccentric and move the coil both vertically and horizontally. They shoul d be used only to center the neck of the tube in the opening of the coil.

TEST SOCKET

A test socket is provided on the rear of the chassis which allows adjustment of the horizontal oscillator and checking of :;ensitivit'y without removing chas sis from cabinet. See Figure 2 for socket connections.


GENERAL

The chassis should be mounte d on angle iron bracke.ts (Motorola Pa"I"t No. 7X7"00210) so that all connections and adjustments may be· made easily.

Since the power cord circuit i s broken by the interlock when the cabinet back is removed, it will be necessary to obtain an extra power cord with the female interlock receptacle in order to make a power connection to the receiver. Order Motorola Part No. 30B470756.

l. Audio Take-Off & Ratio Detector 2. 4. S Me Trap 3. IF Coils & Mixer Transformer 4. Osc & RF Sections

AUDIO TAKE-OFF & RATIO DETECTOR ALIGNMENT

Equipment Required:

AM Signal Generator: Accurately calibrated (Optional) at 4. 5 me

Adjustable output

DC Meter: Low range electronic voltmeter .

Procedure:

Refer to Figure 4 for location of adjustments.

1. If possible, it is desirable to align the audio section from an actual station signal, since the 4. 5 me alignment frequency will be exact. The fine tuning trimmer should be turned off the station slightly, to prevent overloading the ratio detector.

2. If a signal generator is used, tune it accurately to 4. 5 me, and adjust the output to approximately 10,000 microvolts. Connect the high side of the s ignal generator through a 1000 rnmf capacitor to the grid (pin 1) of the video amplifier tube V-7 (6AH6), and the low side to chassis. The following applies whether the station signal or signal generator is used.

3. From either side of capacitor C-52 (10 mf), connect an electronic voltmeter to chassi s decoupled thru lOK ohms.

4. Set the contrast control for maximum gain (fully clockwise).

5. Peak L-20 for maximum reading on meter.

6. Peak T-3 primary (top core) for maximum reading on meter.

7. Move the meter and decoupling resistor from C-52 to junction of R-41 (33K) and lead to volume control.

8. Adjust T-3 secondary (bottom core) for zero response on 2. 5V scale of meter. This corresponds to the cross-over point on the FM detector curve .

If desired, the symmetry of the curve may be checke d by tuning the signal generator 25 kc above and below 4. 5 me and noting the plus and minus voltage produced, reversing the meter connections as necessary. Fo.r proper balance of the ratio detector system, the voltage in each direction should be approximately equal. lf not, check the tuning of L-20 and

the primary and secondary of T-3. the ratio detector. If nec., s sary, replace the ratio detector tube V-9 (6ALS). It is d .. sirable to calibrate the generat<Jr on a station signal. This may be done" by nulling the secondary on a station signa] and then connecting the generato.r and tuning it to produce the same null without touching the trimmers in the set.

NOTE: As the adjus.trnents are brought to resonance, it is advisable to reduce signal generator output to prevent over loading.

With a 10, 000 microvolt sign\'1 into the grid of the video amplifier tube, with the contrast control turned fully clockwise, and the focus control at center of its range, the voltage read from one side of capacitor C-52 should be greater than 5. OV.

4. 5 MC TRAP ALIGNMENT

l. Connect the high side of the signal generator through a 1000 mmf capacitor to the grid (pin l) of the video amplifier tube V -7 ( 6AH6), and the low side to chassis.

2. Connect the voltmeter and germanium crystal rectifier, as shown in Figure 5, between the cathode of the picture tube (yellow lead) and chassis. Use the lowest voltage scale on the m e ter.

3. With the signal generator accurately set at 4. 5 me and maximum output, adjust trap L-18 for minimum reading on the meter.

IF AMPLIFIER ALIGNMENT

Equipment Required:

IF Sweep Generator meeting the following requirements:

18 to 30 me, approximately 12 me swe ep width. Output constant and adjustable to at least • l volt maximum with accurately calibrated, adjustable markers.

Cathode Ray Oscilloscope: preferably one with a c a librated input attenuator.

NOTE: If there is no built-in m a rker in the swe ep ge ne rator, loosely couple the output of an accurately calibrated AM signal generator to the IF strip. At all times, keep the marker output low enough to pr e vent the marker from distorting the response curve.

If a wide band scope is used, the marker will be more distinct if a c apacitor of 100 to 1000 mmf is placed across the scope input. Use the smallest size possible, since too large a value will affect the shape of the curve.

Procedure :

1. R•·move high voltage generator tube V -17 ( 6BQ6GT) from its socket to eliminate horizonta l pick-up in the

oscilloscope. Replace 6BQ6 tube with dummy load of 2500 ohms 25 watts connected from B plus side of fuse to chassis.

2. By means of an external battery, apply a negative 3. 0 volt bias from the bottom of the lst IF tube grid resistor R-13 (6800) to chassis.

3. Using leads as short as possible, connect the hot side of the sweep generator to the grid (pin 1) of the lst IF tube V-3 (6AU6) through a 5000 mmf capacitor (do not use the loose or "spraying" method of coupling). The low side is connected to chassis. Set the center frequency of the sweep to about 24. 6 me and adjust initially for a sweep deviation of approximately 12 me. However, a sweep of from 8 to 10 me may be found better for overall alignment.

4. Using R-26 (lOOK) as a decoupling resistor, connect the scope to pin 4 of test socket. If a stronger output is desired, connect the scope between the picture tube cathode and chassis. The curve seen at this position will be the reverse of the polarity shown in Figure 6.

5. Set the contrast control at minimum.

NOTE: If a distorted or unstable picture is seen on the the oscilloscope during alignment, it may be necessary to stop the oscillator by disconnecting resistor R - 9 (1500) from the plate (pin 6) of the oscillator tube V-2B (12AT7), or.by substituting

another tube with pin 6 removed.

CAUTION: l. Do not reduce the oscilloscope gain and increa~e signal input so that the top of the curve is flattened, due to -limiting in the video or scope amplifiers.

2. The · dress of plate & grid components in the lF affects tuning. Do not move indiscriminately.

3. On the IF coils and on the traps, the resonance point will be found attwo settings of the slug. The correct setting is the one which is found with the greater part of the adjusting screw out of the coil.

NOTE: The lst & 2nd IF traps are tuned from bottom of cpassis, while IF cores are adjusted from the top .I'

6. Tune the low frequency trap L-14, located on the 2nd IF ·coil, for maximum attenuation on the curve at 21. 9 me.

7. Tune the ):ligh frequency trap L-12 located on the 1st IF coil fpr maximum attenuation on the curve at 27. 3 me.

8. AdjustthelstiFcoil, L-ll, to place a 26.6 me marker on the high side of the response curve 60% down - , -

from maximum response. See Figure 6.

9. Adjust the Znd IF coil, L-15, to place a ZZ. 7 me marker on the low side of the response curve 60'% down from maxitru:lm response.

l 0. Adjust the 3rd IF plate transformer, T -Z, to provide a flat top or symmetrical response curve.

11. Reset the traps (steps 6 & 7) and again check the IF for proper response.

NOTE: It is suggested that the bias be removed for accurate resetting ·of the traps.

l z. With bias applied, connect the sweep between the grid (pin Z) of the mixer tube V-ZA (lZAT7) and chassis.

13. Disconnect the trimmer, C-14, in LC circuit in the grid of the mixer tube, qr short the trimmer through a 10, 000 mmf ceramic disc type to chassis.

14. Bring both cores of the mixer transformer, T-1, simultaneously from the outside towards the center. The half-way markers should be Z6. 4 me and zz. 9 me. (Figure 7).

NOTE: In aligning the three IF coils, each coil is adjusted individually, but when adjusting the primary and secondary of the mixer transformer, the adjustments should be made simultaneously. The important point to keep in mind is to obtain a flat response curve with as much gain as possible. The sides of the curve should be straight and as steep as possible. Simultaneous adjusting of the primary and secondary is the easiest way to obtain this result. T}J.e transformer by itself is, in effect, tuned for the same pass band as the three staggered circuits. See Figure 7. The only difference in the overall waveform should be that the sides of the overall wave are ·steeper. Constant use of the 50o/o markers (ZZ. 9 me and Z6. 4 me) should be resorted to, since it is absolutely necessary to obtain the proper curve. A slight dip (not exceeding 10'%) is permissible in the mixer transformer response curve.

BANDWIDTH

The bandwidth may be determined by connecting an AM generator to the mixer grid. With the generator frequency at Z4. 6 me, adjust the output for 1 volt reading on a VTVM

21.9 27.3

FIGURE 6. IF RESPONSE CURVE

21.9 27.3

FIGURE 7. OVERALL RESPONSE CURVE FROM MIXER

connected at the plate (pin Z) of the video detector tube V -6 (6AL5) and chassis. Double the output of the generator. Now, by tuning either side of Z4. 6 me and noting the frequencies at which th~ VTVM again reads 1 volt, the 6 db bandwidth points are indicated.

REGENERATION CHECK

After the above IF and mixer transformer alignment has been made, a check for regeneration in the IF amplifier should be made. This is done by removing the battery bias and observing the output response curve on the oscilloscope, as taken between the picture tube cathode and chassis. The bandwidth may change with the bias removed but should not change more than 0. Z me. Set the contrast control to maximum gain. Decrease the input until the output signal shows a marked decrease. Any regeneration present will be indicated by sharp peaks on the overall response curve. The oscillator should be stopped, as described above, . during this procedure.

CAUTION: Do not inject too much marker signal.

MIXER LC ADJUSTMENT

Reconnect bias removed for regeneration check. Replace trimmer C-14 in LC circuit of mixer grid or remove 10, 000 mmf ceramic between trimmer and chassis. Adjust the trimmer so it is tuned to the center of the mixer response curve. This is indicated by observing the effect of the LC circuit on the mixer response. In~reasing the capacity of the trimmer and bringing the LC circuit from above the IF range into the IF range, it ·will be noted that the mixer

curve will pull down on the high side, then straighten out as the LC circuit approaches the middle of the range, and pull down on the low side as the LC circ•.dt approaches the low end of the 1F range. The proper tunin-g point is that p·oint at which the mixer curve straightens <>ut. In effect, the LC circuit is similar to a jack coil when it is within the IF range.

CAUTION: Tuning the LC circuit very low will cause oscillation.

IF SENSITIVITY MEASUREMENTS

IF Stages Only

1. Remove the battery bias from the lst IF tube grid.

2. Connect an AM signal generator, set at 24. 6 me thru a blocking capacitor of 5000 mrnf, between grid (pin I) of the lst IF tube V-3 (6AU6) and chassis.

3. Connect an electronic voltmeter across the video detector load resistor R-28 (5600). Both leads from the meter should be decoupled with lOOK ohm res istors.

4. Set the contrast control for maximum sensitivity.

5. Stop the oscillator tube by disconnecting resistor R-9 (1500) from the plate (pin 6) of the tube V -2B (12AT7) or by substituting another tube with pin 6 removed.

6. The signal required to produce 1 volt (negative) above contact potential on the meter should be less than 700 microvolts.

Mixer & IF Stages

The preliminary preparations are the same as for checking the sensitivity of the IF stages except:

I. Connect the AM signal generator, set at 24. 6 me, through a 5000 mmf capacitor, between the grid (pin 2) of the mixer tube V-2A (12AT7) and chassis.

2. The signal required to produce 1 volt (negative) above contact potential on the meter should be less than 125 microvolts.

1. Remove high voltage generator tube V -17 ( 6BQ6GT) from its socket and replace with a dummy load 9f 2500 ohms 25 watts connected from B pLus side of fuse to chassis. Stop the oscillator by disconnecting R-9 (1500) from plate (pin 6) of V-2B {12AT7).

2. Connect the sweep generator across the antenna termi-;,als on the chassis with the antenna lead-in re• moved. The line from the sweep generator should be as short as possible.

3. Connect the oscilloscope through a decoupling resistor of 150, 000 ohms, between the cathode (pin 3) of the mixer tube V-2 (12AT7) and chassis.

4. Short out the AGC circuit with a clip lead from the AGC bus to chassis.

5. Refer to Figure 4 for the RF trimmer location and to Figure 9 for the locations of the antenna and RF coils. The frequency chart listed previously gives the channel and alignment frequencies.

6. The antenna coils are tuned to the video carrier frequency and the RF coils are tuned to the sound carriers. Figure 10 shows the shape of the curve which should appear on the scope for channels 2-6 and Fig-ure 11 the curves for channels 7-13. ·

7. Turn the station selector switch to channel 10. Set the center frequency of the sweep generator to the center frequency of channel 10 (195 me).

8. Adjust ceramic trimmer, C-6, so that picture and sound markers arc as in Figure 11.

9. Check channels 7 to 13 for proper response and, if necessary, tune the coil L-6. These coils may be tuned by spreading them to decrease inductance or compressing them to increase their inductance. See Figure 9 for location of coils. This will have more effect on channels 10 to 13 than 7 to 9. If L-6 is adjusted, it may be necessary to readjust RF trimmer C-6, and recheck the high channels.

NOTE: As the bandwidth of the high channels is very broad, a slight variation is permissible.

10. Move bandswitch to channel 6.

11. With the center frequency of sweep generator at the center frequency of channel 6 (85 me), introduce markers corresponding to sound and picture carriers and compare with curve of Figure 10.

FIGURE 9. ANTENNA, RF AND OSCILLATOR COIL LOCATIONS

NOTE: A convenient method of determining whether a coil is tuned correctly is to insert a brass or iron slug into the coil. Brass decreases and iron increases the inductance.

12. After channel 6 has been aligned,. progress downward through channel 2.

CAUTION: Make certain the s tation selector switch is on the correct channel before checking bandpass.

OSCILLATOR ADJUSTMENT

1. Put oscillator back in circuit.

2. Remove the short from the AGC circuit and apply a -3 volt battery bias to the AGC bus.

3. Move the scope to the test socket on the chassis rear with the high side connected to pin 4 and the low side to pin 5 (chassis).

4. Set the contrast control at minimum (counterclockwise).

5. Remove the fine tuning knob and turn shaft until the slot is in a horizontal position. This represents the mid-capacity position.

6. Turn station selector switch to channel 12.

7. Set the sweep generator on channel 12 with a center frequency of 207 me and at least a lZ me sweep. Keep the output low enough to show no evidence of limiting in the overall response curve.

NOTE: Before aligning the oscillator section, make

FIGURE 11. RF RESPONSE CURVES CHANNELS 7-13

certain the 3. 3 microhenry choke (L-8) in the mixer grid is dressed away from the 2 mmf capacitor (C-16) tied to the same grid.

8. Introduce a marker corresponding to the sound carrier of channel lZ (Z09. 75 me).

9. Adjust oscillator ceramic trimmer so that the sound marker falls into the 21.9 me trap dip in the response curve.

10. Turn generator and station selector to channel 9 with the fine tuning shaft slot still in the horizontal position.

11. Spread or compress the 3-turn coil located in the center of the oscillator plate (L- 4M, Figure 9) so that the sound marker for channel 9 falls into the Z7. 3 me trap dip in the response curve. As the oscillator is tuned below the carrier on channels 7, 8, 9 & 10, the Z7. 3 me trap will be in the same position as the Zl. 9 me trap in step 9.

lZ. Repeat steps 6, 7, 8 & 9.

13, Turn generator and station selector to channel 13.

14. Turn fine tuning trimmer so that the sound marker for channel 13 falls into the Zl. 9 me trap dip of response curve. The slot in the fine tuning shaft should not have moved more than 30° from the horizontal position to accomplish this (each number on the station selector knob represents 30°).

15. U more than a 30° change in fine tuning trimme r was needed in step 14, adjust channel 13 oscillator coil

9


(L-7) by spreading or compressing until the 30° requirement is met.

NOTE: Each adjustment of channel 13 oscillator coil (L-7) will necessitate a rechecking of the oscillator trimmer on channel 12 as per steps 6, 7, 8 & 9.

16. Check channels 12, ll, 10, 9, 8, and 7 by noting whether the fine tuning trimmer can drop the sound marker for each channel in the trap dip by a 30° rotation. If one of the channels does not meet the 30° requirement, a compromise must be made by resetting channel 9 or 12, whichever is closer to the channel in question.

Example: 1) Ifchannellldoes notmeet the30°requirement, return station selector and generator to channel 12 and tune ceramic trimmer toward channel ll (trimmer frequencies lowered by tightening screw). This will tend to move channel 12 sound marker out of the trap dip, but this can be compensated for by the fine tuning trimmer. Do not adjust trimmer any more than is n e cessary to get the channel in question back within the 30° requirement.

Example: 2) If channel 10 does not meet the 30° requirement, move station selector and generator to channel9 and tune the 3 -turn coil (L-4M, Figure 9) toward channel 10 (coil freq raised by spreading turns.) This will also tend to move channel 9 sound marker out of the trap dip, but this can be compensated for by the fine tuning trimmer. Again, do not adjust the coil any more than is necessary to bring the channel in question back within the 30° requirement.

17. Turn sweep generator and station selector switch to channel 6.

18. Adjust channel 6 oscillator coil (L-4E, Figure 9) so that the sound marker for channel 6 falls into the 21. 9 me trap dip with the fine tuning trimmer at midcapacity (shaft slot in horizontal position). Always spread or compress channel 6 oscillator coil in units of 3 turns. Compressing turns will move curve toward s ound marker, while spreading will move

CIRCUIT

Chassis TS-ll4 and TS-ll5 are electrically identical except for the Vertica l Sweep Generator (V -13). l'he TS-ll4 uses a 6SN7GT instead of the 12AU7 of the TS-ll5. This change necessitated changing grid resistor R-63 from 330K

10

curve toward video marker.

IMPORTANT: Since the coils are in series, the proper alignment of channel 6 will simplify the phasing of the channels to follow.

19. Adjust channels 5 and 4 so that the sound marker for each channel falls into the 21. 9 me trap dip in the curve with the fine tuning trimmer set no more than 15° from mid-capacity,

20. Channels 3 and 2 should be adjusted so that the sound marker falls into the 21. 9 me trap dip with the fine tuning trimmer within 15° of maximum' capacity.

OVERALL RECEIVER SENSITIVITY MEASUREMENT

An overall measurement of sensitivity is made as follows:

1. Connect an AM signal generator to the input terminals of the receiver chassis after removing the short 300 ohm lead which connects to the antenna input strip on the back of the cabinet. To match the generator to the receiver input, a resistor matching network should be used. In the case of a generator with a 50 ohm output impedance, for example, place a 100 ohm resist<>r in series with the output terminal of the generator and a 150 ohm resistor in series with the ground terminal,

2. From cathode of picture tube to chassis, connect a calibrated oscilloscope,

NOTE: To calibrate scope, connect it across 6, 3 volt filament supply. The peak-to-peak amplitude on the screen will then be approximately 18V ( 6. 3 X 2, 8),

3. Set contrast control for maximum sensitivi-ty.

4. Tune signal generator to the video carrier frequency of the channel being checked. Generator signal should be 30% modulated at 400 cycles, The signal from the generator to produce 20 volts peak-to-peak at picture tube cathode should be less than 25 microvolts on channels 2 to 6 and less than 75 microvolts on channels 7 to 13.

DESCRIPTION

to lOOK. The circuit description of the TS-ll5, as foand in the TS-ll5 Service Manual will, therefor<;, apply al.so to the TS-ll4 except for the differences noted above.

CHASSIS TS-114A

SERVICE MANUAL SUPPLEMENT (SUPPLEMENT TO TS-114 SERVICE MANUAL· 54P701933)

NOTE: This Service Manual supplement contains schematic diagram and supplementary parts list covering the TS-ll4A TV chassis. Alignment data, service adjustments, etc., for this chassis is identical (with the exception shown below) with the TS-114 and will be found in the TS-114 Service Manual, Part No. 54P701933.

MODEL 14T3Xl is identical to Model 14T3. Refer to 14T3 Service Manual, Part No. 54P701933 for replacement parts.

REVISED HORIZONTAL OSCILLATOR ADJUSTMENT

(FOR TS-114A)

The Horizontal Hold control s hould have a sync range of approximately 180 degrees. If the control is too critical, ad-

just as follows:

1. Short out Horizontal Oscillator coil L-23. This may be done by shorting the 2 pins of the receptacle (terminal strip in some sets) on top of the chassis.

2. With the centering lever, move the picture to the left so that the right edge of the raster can be seen. Adjust the Horizontal Hold control to about the middle of its range and note the width of the blanking pulse. (The blanking pulse appears as a gray bar at the right edge of the pic\_ure).

3. Remove short from Horizontal Oscillator coil.

4. Adjust Horizontal Oscillator coil until the same amount of blanking pulse can be seen as was noted in Step 2.

REPLACEMENT PARTS LIST SUPPLEMENT ·NOTE: When ordering parts, specify model and chassis number of set in addition to part number and description of part.

The following parts are replacements for or additions to the original items listed in the TS-114 Service Manual.
