AMPVHF - Homebrew 432 1000W + Amp This is a Homebrew 432 cavity amplifier built from a modified Rockwell Collins AM-6727 KW aircraft amplifier. It uses a RCA 4661 coaxial ceramic tube which is the same thing as RCA 7213 1100W out with 45W of drive. Well built and rugged power supply running 3500V at around 690 mA. This thing should be bomb proof and was built with the intent of running EME duty cycles. This is very well built and I had it built for me and then never used by me except one time to test. Only reason I'm selling it is that outside of EME 432 has no allure for me and the money would allow me to do some different things that I am more active at on ham radio. I also have two more of these kilowatt cavity aircraft amplifiers. $1,200 for the working amplifier and power supply. If you want the other two amplifiers or spare tube we can discuss that.
