3CW7000F7

The 3CW7000F7 is a ceramic/metal,water cooled, high-mu triode intended for use as an amplifier, oscillator, or modulator, or in voltage regulator applications. Its maximum rated anode dissipation is 7000 watts. The 3CW7000F7 is a water-cooled version of the air cooled 3CX3000F7, and is identical except for the addition of flexible leads on the base for grid and filament connections, which can simplify socketing in lowfrequency operations. Operation with zero grid bias in many applications offers circuit simplicity by eliminating the bias supply.
