Abstract

222,981. Voigt, P. G. A. H. July 17, 1923. Thermionic amplifiers. - In a low-frequency power amplifier, the ends of the secondary of the input transformer T are connected across the grids G of two valves arranged differentially, a connection being taken from one end of the secondary to the filament through a high resistance R (or other impedance) and biasing cells C. Each half cycle of the input voltage throws one or other of the grids positive, whereupon the resultant grid current automatically regulates the initial grid bias proportionally to the impressed voltage. By suitably adjusting the permanent bias from the cells C each valve can be used to amplify both halves of the input wave. In the case of an overload both valves become operative without giving rise to distortion. Should distortion occur it is accompanied by rectification, and this is shown on the indicator M. For smaller voltages only one valve is used, a condenser being inserted in the circuit in place of the grid-filament path of the second valve.
