Abstract
337,155. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Sept. 30, 1929. Thermionic amplifiers. - Each filament of parallelconnected amplifying-valves 1, 2, with directly connected plates is heated separately and is connected to the common grid circuit 12 which is traversed only by the plate current of the corresponding valve through a resistance 10, 11. The filaments are supplied from a transformer 6 with one primary 7 and a separate, secondary winding 8, 9, the middle points of which are connected to the respective resistances.
