Abstract

590,443. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 19, 1945. No. 9897. Convention date, Jan. 16, 1943. [Class 40 (v)] In a push-pull amplifier, amplification of in-phase voltages present in the input is reduced by capacitatively feeding back the anode potential of one valve into the cathode circuit of the other. The Figure shows an arrangement in which two capacitors 42 and 44 provide the feedback required.
