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 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.

Rebuit with Eimac Core

This 3CX3000A7 tube has been rebuilt, tested and meets all technical specifications expected for new tubes. The Warranty period for this tube is Ninety Days from the date of purchase, for the original customer only.  Please follow the instruction insert for proper installation.
