3CX3000A7

The Penta 3CX3000A7 tube for sale is a high-mu metal/ceramic external anode power triode. Maximum plate dissipation for this tube is 4000 watts, and cooling is forced-air. At moderate plate voltages, relatively high power output can be obtained from the 3CX3000A7 tube for sale as an amplifier, oscillator, or modulator.

For grounded-grid operation, excellent shielding between the input and output circuits is provided by the grid, handily terminated between the filament and plate terminals. A power gain of approximately 20 times can be obtained under operation with zero grid bias. The 3CX3000A7 amplifier tube for sale is designed using a rugged, lowinductance cylindrical filament stem, making it especially well suited for use in the linear filament tank circuit under VHF operation.
