I believe it's 235-240v B+, close is good; and the heater voltage. Look around the net for the RA-20 P/Supply specs. Check for B+ rail to ground shorts before you hook it up though.

Years ago, I had a brand new BC-342 packed in a shipping crate that had an onboard 110VAC power supply built in. 

Maybe someone took this guy's PS out?

The 250V B+ sounds about right.  I felt it once or twice...

Hey Tim,

     TM 11-850 is online at:

http://www.pestingers.net/PDFs/Other_radio_stuff/Military%20manuals/TM%2011-850%203%20Sep%2046%20NJ7P%20AS.pdf


      The RA-20 is nice but the RX often had a DM-21 dynamotor for 12VDC
or a DM-21CX for 24-28VDC.

Basically, they're the same box.
