| cpi | 3cW20,000H7 cpi|4cW50,000J 3cW20,000H7 The 3CW20,000H7 is a high-mu power triode intended for use as a dc voltage or current regulator, or in a high voltage switch tube or pulsed regulator service. In addition, since the tube is identical to the 3CW20,000A7 except for the anode and grid flanges and the addition of the filament flying leads, it is useful as a zero bias Class B amplifier in audio or RF applications. cHaRacteRistics Plate Dissipation (Max.)
