Found it with some help from Norm. I went back to look at the candohm replacement I had made. And there it was.
Re-examining the candohm forced me to trace all of the attached leads to their components and I found the issue (which was a basic power supply problem). I had stupidly followed the original techs' lead dressing, and therefore I had C27A and C62 switched.
How it worked at all amazes me. I took the filters out, redressed them, and carefully followed the schematic to install them one at a time. Right now the set is singing beautifully on my bench. I'll let it run for a while to see if anything else comes up, but I'm impressed with the sound of this set. I bet when I get it back in the cabinet behind the grill cloth and bolted in, it will sound amazing.
