RCA 7213 AF High power High frequency Transmitting Tube Ceramic. NOS 7213
is rare and desirable for use at UHF 1.5KW. Unused, good filament and no
shorts. Coaxial socketed tubes. They are supposed to be a good tube for
around 1200 MHz but are excellent for 432 MHz. These are HUGE and have a
very large anode similar in diameter to an 8877 but not as tall. They have
a
pink cermamic on the sides. These tubes cost thousands of dollars each
when
new. http://www.surplussales.com/Tubes-So...eSpecials.html I was
going to use it for a project, never got around to doing it.
