8122 Transmitting Tube, Linear Beam Power Tube, MFR: RCA  No longer available for Export, (NOS)

The 8122 is a very small, low-cost, forced-air-cooled beam power tube designed for use as an RF power amplifier, oscillator, regulator, distributed amplifier, or linear RF power amplifier in mobile or fixed equipment. The 8122 features a light-weight, cantilever-supported cylindrical electrode structure within a ceramic-metal envelope. This construction provides a very sturdy tube and permits high temperature operation.

The 813 beam power tube was very popular with amateur radio operators following WW II. The tube remained a staple of amateur radio until single sideband became a popular operating mode in the late 1950's and early 1960's. Featuring a graphite plate with an ICAS dissipation rating of 125 watts the tube was very economical and a pair could provide legal limit operation (1 kilowatt input) on CW or AM. Later tubes manufactured by RCA and Amperex featured an improved plate made of zirconium-coated nickel.
