Abstract

295,501. Igranic Electric Co., Ltd., Wright, S. R., and Currah, L. E. July 21,1927. Thermionic amplifiers.-In amplifiers supplied with high tension from rectifiers, the rectifiers are connected in series, and grid bias for one of the amplifiers is tapped from the output of the rectifier supplying high tension to another amplifier circuit. The Figure shows rectifiers r1, r2, having output circuits 1, 2, and 3, 4 supplying high tension to valves v1, v2, the filament of the latter being heated with alternating current. A tapping on a resistance s across the output 1-2 supplies the grid bias to the valve v2 and additional tappings may supply high tension voltages for other valves in the set. An additional potentiometer connected across a portion of the resistance s may be used for the grid bias tapping.
