3CX 6000A7 / YU -148

      The 3CX 6000A7 / YU -148 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 stem structure which readily becomes part of a linear filament tank circuit for VHF operation. The grid provides shielding between the input and output circuits for grounded grid applications and conveniently terminates in a ring between the plate and filament terminals.
