| cpi | 3cx20,000a7 cpi|4cW50,000J 3cx20,000a7 The 3CX20,000A7 is a high-mu power triode intended for use as a zero bias Class B RF amplifier or Class C power amplifier or oscillator. Class B operation with zero grid bias offers circuit simplicity. In addition, grounded grid operation is attractive since a power gain as high as twenty times can be obtained. cHaRacteRistics Plate Dissipation (Max.) Screen Dissipation (Max.)
