Terry,
That is great news! I will let you know...
I got ambitious just a 1/2 hour ago and put the RAS back on the bench supply, upside down. Did the cursory look around the BFO area, spotted a 220k 1/2w dogbone broke off the terminal shared by the gimmick cap. I'm sure that is what has killed the BFO, I'll repair tomorrow and test with the refurbished power supply.
Spent some 5 hours on that power supply scrubbing out potting wax yesterday. All clean and saved the paint job. Today I scrubbed/polished the cover for the P.S.
I have been led to believe that this radio spent its previous life tuned to 500khz 24/7, at the New Bedford airport, then stored in a bit of a damp location... To be placed in a local Ham flea in the 70's, passed by for hours until I came along, it was tagged $5...
FWIW all the caps are contract Aerovox New Bedford. Others are Cornell suspect N.B. as well.
