| cpi | 3cx400a7/ 8874 cpi|4cW50,000J 3cx400a7/8874 The 3CX400A7/8874 is a compact high-mu power triode intended for use in zero bias Class B amplifiers in audio or RF applications. Operation with zero bias simplifies circuitry and cathode driven operation is attractive since a power gain as high as twenty can be obtained. cHaRacteRistics Plate Dissipation (Max.)
