Filed: 1929-02-11
Abstract: 305,944. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Roberts, W. van B.). Feb. 11, 1928, [Convention date]. Thermionic amplifiers deriving their plate and grid voltages from a potentiometer 2 connected across a fictuating direct current source 1, have each plate connected to two separate tappings, one serving for direct current, the other for the alternating or hum compound, and the latter is so chosen that the hum effect in the plate circuit is counterbalanced by a hum effect in the grid circuit. As shown for a two-valve low-frequency amplifier, the filament of the output valve 25 is connected across adjacent tappings 33, the grid derives its bias from a tap 30, and the plate is connected through two separate paths to taps 31, 32. The path from 31 includes an audio-frequency choke 27 and therefore carries only direct current, whilst the path from 32 includes a condenser 28 and carries the hum or alternating current. The tap 31 is chosen to give the desired working voltage on the plate, having regard to the grid bias supplied by the tap 30. The tap 32 is chosen so that the ratio of the voltage at that point to the grid voltage is equal to the amplification factor of the valve. Similar connections to taps 30<1> - - 33' are made for the valve 25<1> and for any other valves in the set. The filaments may be connected in series between portions of the resistance 2, but the arrangement shown has the advantage that the failure o,f one filament does not cut out the remainder.
