I have a BC-640B transmitter. It has two identical power supplies. One is missing, but it's very simple and I believe I have a chassis, panel and some of the iron for it. I also have a spare modulator, which is two 811As.
There's some info here:
https://amfone.net/Amforum/index.php?topic=32423.050W carrier, AM (200W peak). crystal controlled so it could be FM'd without too much trouble. But it's a proect. Currently standing in my laundry room with everything in the rack except the one power panel, and the spare modulator.
If you want big iron this is it, 600 Lbs I believe. I loaded it all in the van once the rack chassis were pulled. The wiring harness is complete as far as I can tell. I also have the autotransformer for it.
In this mesage is a decent image as it sits pretty much
https://amfone.net/Amforum/index.php?topic=32423.msg323647#msg323647I have manuals for it. electronically. too big to e-mail.
Is it a "good" vintage military 2 meter transmitter? Yes if you don't mind doing some work on it.
