Abstract

614,813. Valve amplifying circuits. PHILIPS LAMPS, Ltd. Aug. 1, 1946, No. 22923. Convention date, May 30, 1940. [Class 40 (vi)] A tube having two succeeding secondary emission electrodes 5, 11, of which the last 11 is connected to the anode 6 through an output impedance 8 whose electric centre 10 is connected to the cathode 2, is provided with a back-coupling from the preceding electrode 5 to the control grid 3 so as to reduce the damping of the input circuit 7 and to decrease the input capacity. Fig. 4 shows a push-pull arrangement in which the output electrodes 1, 11<1> and 1<1>, 11 are interconnected by condensers 13, 14.
