The 8875 is a compact high-mu power triode intended for use in zero bias Class B amplifiers in audio or RF applications. The 8875 has a transverse cooler for forced-air cooling and is rated for 300 watts. Operation with a zero grid bias simplifies circuitry by eliminating the normal bias supply. In addition, grounded grid operation is attractive since a power gain as high as twenty can be obtained.
