This is a Amateur Radio (Ham) UHF (1.2Ghz or 23cm band) high power, water cooled RF amplifier.
I built it from these plans: https://www.w6pql.com/23cm_amplifier.htm

It will output ~300 watts on the 23cm amateur radio band. It uses the reliable Russian GS-15 ceramic vacuum tube.
This amplifier comes complete with high voltage and filament power supply, water cooling system and a spare GS-15 tube.

The amp was last used about 5 years ago and has been in storage. I was very successful using it during VHF/UHF contest and EME or moon bounce communications.

I will not ship. Very heavy. Would consider meeting at a location in central California.
