Used EIMAC 3CX1200A7 - full power. I just pulled this from a working AL-1200. The used serial is JTD-544. $525.00 shipped and insured (Only to the lower 48 states). The 3CX1200A7 is a high-mu, forced air cooled, rugged power triode intended for use as a zero bias Class AB2 RF amplifier to 110 MHz. This tube is a workhorse and forgiving as well. Instant on in 10 seconds. The new 3CX1200A7 is no longer available. I am willing to barter to some degree. Looking for an Ameritron ATR-30 antenna tuner or a clean Tarheel II Little screwdriver antenna, mount and screwdriver controller for a ICOM 706mkIIG. Contact me if interested.
