Abstract

491,063. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 19, 1938, No. 11757. Convention date, April 21, 1937. [Class 40 (v)] In a valve having a heated cathode 2, at least one control grid, an anode 5 and an auxiliary electrode 6 emitting secondary electrons, the output impedance 12 is connected between the anode and secondaryemitting electrode and an intermediate point of the impedance is connected to the cathode. The positive voltage on the secondary-emitting electrode is determined by a resistance 14 shunted by a condenser:
