CPI 3CX15

The 3CX15,000 A7 is a high-mu power triode
intended for use as a zero bias Class B RF amplifier or Class C power amplifier or oscillator. It is
also recommended for use as a grounded grid FM
amplifier. Class B operation with zero bias offers
circuit simplicity. In addition, grounded grid operation is attractive since a power gain as high as
twenty times can be obtained.
