What you need is some kind of interupter, I have put 275 DC on the "B +" by passing the power supply and make the radio work, I did this once on a 8 tube 1955 Ford radio, had BAD noise interference, noise went a way with original power supply out, turn out to be that some one had put in the wrong vibrator hash. I had gotten this radio when I bought out an old radio repair shop, they had written "JUNK" on it , they couldn't figure out what was the problem , sometimes it just takes time and experimenting, BILL
