This thing is called an AM-6155 or AM-6154. These things were made as part of a VHF radio set for the military and other government users. A lot of them were used by the FAA (Federal Avation Administration) for aircraft band communications.
The AM-6154/6155 uses a vacuum tube so it is obsolete. But it makes a good amplifier for the 144, 220 or 440 Mhz ham bands. I’ve been trying to set up a 144 Mhz SSB/CW station and I want to convert this amp to that use. There are various sites on the web which have conversion details.
Mine actually came from Hawaii. A guy on a mailing list said he wanted to get rid of it and I offered to pay for shipping. You can buy one from a real vendor if you want: go to www.fairradio.com and put AM-6154 in the search box. It comes up for $450. (So if mine works I got a very good deal.)
Properly operating, it is supposed to turn my 10 watts into 400 watts. That would be a much bigger signal.
I have some study to do. This will probably be a fall/winter project.
