  2. 813 RCA Transmitting Tube (Pull)

    813 RCA Transmitting Tube (Pull)

    $93.91

    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.
