CPI 3CX800A7

The 3CX800A7 is a compact high-mu power triode
intended for use in zero bias class B amplifiers
in audio or radio frequency applications. It may
also be useful as a pulse modulator or regulator.
A single 3CX800A7 will deliver 750 watts PEP
and 750 watts keydown CW output to 350 MHz.
Linearity and power gain are excellent due to the
beam forming geometry of the special grid and
cathode design.
