Reafizing the disadvantage of the six wolt storage battery for flament Ught- to do tn applying 110 volt current ts to reduce it to a point where it can be ap- plied to recetving tubes which take ap. proximately one ampere of current at about five volts, This can be done by using two resistances, one large one of 100 ohms and one small one of fifteen ohms in the form of a rheostat, The constant reduction of the larger resist- ance gives a nice margin for the varia- tion of the rheostat so that the proper adjustment is obtainable. The filter circuit is one on which a great deal of experimenting has been done, and it wes found that the simple filter gave better results than the more complex ones, The circuit consists of one condenser of one microfarad ca. pacity and one iron core choke with an inductance of Atty militheur! The condenser is placed directly ac the 110 volt Ines, and the fron cove ts put in the positive len!, The choke coll may be made by winding about 120 turns on an fron core of about three square inches in cross section. The relative positions of the reais- tances and their values are shown in the accompanying hookup. The con- denser is placed directly across the 110- volt mains and can be of any type pro- vided the value is correct. The choke cofl gives the best results in the positive main, but tt may also be placed in the negative side, One other adjustment will be found A high resistance of 150 ohms placed across the filament termi- nals in the manner of a potentiometer as indicated in the hookup. The grid connection then be made to the ad- tof the potentiometer.

In experi- menting it has been found that in mov- Ing the adjustable contact to elther ex- tremés of the potentiometer the poorest results have been obtained. The best results showing the least amount of commutator nbises was obtained with the adjustment somewhere near the centre. Good reception can be had with this hookup, which is very inexpensive and practical. Yonkers Radio Fan—What size wire should [ use for @ lead-in?

Is there any difference between these batteries? Answer—Yes, the auto storage battery can be used in of the six volt radio battery. There is a difference in their construction. The auto battery is constructed with thin plates to give a quick and high discharge for the starting of the motor. The ra- dio battery is mado with thick plates so as to give a steady slow discharge at an even rate, The latter of course is to be desired, but In @ pinch the auto battery will do very nicely.
