4CW10-000A

cpi | 4 cW10,000a/ 8661 cpi | 4cW50,000J 4cW10,000a/8661 The 4CW10,000A/8661 is electrically identical to the 4CX10,000D/8171 and 4CX5000A/8170 except for its plate dissipation, which is rated at 12 kW. The tube is useful up to 110 MHz and is suggested for general use as an oscillator, amplifier, or modulator. A pair of these tubes will deliver more than 30 kW of audio output. tube. cHaRacteRistics Plate Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
