Abstract
787,355. Valve amplifying circuits. GENERAL ELECTRIC CO., Ltd., and DRYBROUGH, D. A. S. March 26, 1956 [March 25, 1955], No. 8803/55. Class 40 (6). In an audio-frequency amplifying stage transformer coupled to a loudspeaker, damping on the loud-speaker is increased by feedback from the transformer secondary to a resistor 7 in the cathode circuit via a capacitor 8 which may be electrolytic.
