Description:

The 3CX3000A7 high-mu forced air cooled power triode provides relatively high power output as
an amplifier, oscillator, or modulator at low plate voltages. The tube has a low inductance cylindri
cal 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.
