| cpi | 4CX350A/ 8321 cpi|4cW50,000J 4CX350A/8321 The 4CX350A/8321 has a maximum plate dissipation of 350 watts and is intended for Class AB audio or RF amplifier service. The tube is externally identical to the 4CX250B but contains rugged internal construction features. Amplification factor and cathode area have been increased over the basic 4CX250B to give higher transconductance and figure of merit. chaRacteRistics Plate Dissipation (Max.)
