Strong Battery Voltage Necessary for Speaker Many good sets fail to deliver sufficient suf-ficient volume on the. loud speaker because be-cause they are not supplied with the. necessary power to do so. Forty-five volts on the plates of the amplifiers will not deliver enough current to the magnets of the loud speaker to produce pro-duce loud signals. Ninety volts will give much better results, and is certainly cer-tainly worth the additional cost. An extra grid bias is sometimes necessary with higher voltage, and this Is connected con-nected with 4',2-volt "C" battery, which is connected between the F post of the transformer and the filament. The negative terminal of the battery connects to F and the positive terminal to the filament.
