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.
