 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.
More pictures and details on request and will have at the Magic tailgater swap meet tomorrow in Maple Grove MN.
Looking for KW 6m amp

 Trilectric 2M FM amp, 200W Lower price  
Used Trilectric (Decibel) A40140H FM Amplifier. Tested at 150 Watts plus output on 10W input. Seems to work as it should but excess to my needs. Notes on bottom say 200W linear amp. Could be, my watt meter only goes to 150W, the needle was pegged.
No power cord. $145 (lowered) including shipping CONUS.
Consider trade for Kenwood TS-711a

 Wanted 2m brick amplifier
I recently purchased an Icom IC-705 and I am pretty impressed with it's receive especially on two meters. I am wanting to get it setup in my camper for POTA etc, and I would like to have a bit more than 10 watts.
I already have a brick for 432 and 50mhz, but no longer have one for 144mhz. I am looking for a 10W in and 80-160w output. Working or not. It doesn't have to be pretty, just complete.
I also have a TR-751A listed for sale here on QTH. I might be willing to trade for the right amp. Email a photo of your amp with proof of identity like a QSL card in the photo.
Scammers, don't bother.
