Abstract

491,468. Valve amplifying circuits. HIRSHMAN, C. L., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 21, 1937, No. 17286. [Class 40 (v)] A paraphase amplifier comprises two valves arranged to give a push-pull output, the second valve V2 being coupled to the valve V1 by a capacity potentiometer of which one leg comprises condenser C2, C3 and the other consists of the input capacity of the valve V2 due to Miller effect. Condenser C3 may be adjustable so that the outputs of the valves V1, V2 may be balanced or alternatively an additional condenser C6 may be provided for this purpose. If the input capacity of valve V2 due to Miller effect is made large compared with capacity C2 + C3, then the capacity potentiometer automatically compensates for variations in gain of the valve V2.
