The 3CW7000F7/YU-106 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/YU-

106 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 low-

frequency operations. 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

20 times can be obtained.
