The 3CX3000A7 high-mu forced air cooled power triode provides realtively high power output as an amplifier, oscillator, or modulator at low plate voltages. The tube has a low inductance cylindrical filament tank circuit for VHF operation. Operation with zero grid bias in many applications offers circuit simplicity by eliminating the bias supply. Grounded-grid operation is attractive since a power gain of over twenty times can be obtained.
