Does this answer your question ?

Owne r : Person.,lly I prefer th,. Phiko "A' ®d •·B" A ccumulator Batteries, but a smart sale,-man persuaded me to bu)' an Eliminator 1\ow n1y re•ult. ""' not as good, )'<'l my yearly

high vo ltage. Owner : What about Philco batteries? Expert : There you have absolutely pure D.C. current

without variation, giving the finest reception ) ou can be c;e1tain of Life. Distance, Volume and Clanty,

\ ::::: That wa,i my own experience with Philcos. Now get on to the costs. In using an Eliminator you are working with clectric light c urrent, which fluctunt.-: Fluc tuating cu rrent plays havoe with valves and you cannot blow out costly valves and look pleasant. Of cour6e Eliminators which use l

the new Raytheon tube for ,ec t,fication are more econom1cal than E limmators employing ordinary valves.

Owner : Tha t's a good tip anyhow. Now what about o savmg m charging ?

Expert : Even with an Eliminator you have to buy a Ch11rgtr for your .\ battery. \Vi1h 1he A and B Philco Batteries you also need a Charger, but the cost al recharging •• only a few pence every chree or lour mo ntb,i \\'here d oes the Eliminator save anything >

Owner . Well. if by using the A and B Phileas I can get better results and sav.e money as well, why on earth did I buy an expensive Elimmator ?

Expert : Ask that smar t salesman I I can"t tell you. ! j i
