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.
