Does this look like the part?



The price seems reasonable.

OK, so the award goes to Glen to who called it correctly.?

Though the problem manifested itself as low 12V, the issue was in the -10V supply.? This caused a 120Hz pulse in the -5.6V (approx.)?voltage to the reference circuit?for the 12V regulator.? I didn't have the correct cap but I swapped in a 4,000uf (13,000uf required) and up it came albeit with noise sidebands from the lack of filtering.

So where can I find a MEPCO/CENTRALAB 13,000UF 25Vdc 30 surge cap?

Thanks for all the help.?
