Well, I finally got back to the 6700 this weekend.
I followed Overundr1’s advice and put OP TRs A&C in the Right Channel and B&D in the left. I used new mica washers and applied just a smidgen of white thermal paste to both sides, then pressed them to the back of the TRs.
Once everything was secure I went back and rechecked the wiring continuity between every OP TR pin and the lead of a component on the F-2980 bd that it should be wired to. Don’t want to have to go back in later to correct something I had overlooked.
Checked out the switch on the F-2853 bd that I cleaned earlier and it seems OK.

My new 3058 bds have a slightly different pin layout and I moved the emitter resistors to the track side. All designed to make it easier to get the boards into their mounting positions, and it helped a lot. I used a dental pick to align the holes in the mica washers with the holes in the TRs and the mounting holes.
