Dave, you're a man after Dick Slade's heart. He's the guy who was so kind to give me that RCA 630TS that I restored. He wanted to just "plug her in & let her rip."
I plugged her in, without the 5U4's, just to see her light up all the tubes. I didn't try to reform the electrolytics, because I figured some were beyond hope (I was right).
I did heat up the chassis, upside down, with a heat gun to chase away any condensation, heat up the resistors, etc. After that, I just started replacing all the electrolytics & tube capacitors.
Call it overkill, but the thought of wiping out an unobtainium part(s) was overwhelming...
Ahhhh. I feel better. Now, on to the Next Project.
