Hi Lew, I was seeing the same thing today. I was inspecting all the solder joints and some of them look awfully close. I like your idea as I couldn't come up with one.
Follow Ups:
Just realized that in many cases, if not most, you can just de-solder, install a piece of heat shrink to cover the exposed joint, then re-solder and use the heat gun. No need to install so many stand-offs.
Hi Lew. Working in the shop today I found a can of Plastic Dip and wondered if I could just paint the bare joints with this stuff. I called the company and they said once dry it can stand temperatures of 200+ degrees then I called a shrink tube company and they said the same for shrink tube.
I think I will just paint the bare joints with Plastic Dip. Thoughts ?
Good idea. Those connections are on the cathodes, which could have high voltage though. I would think that Plasti-Dip would have a high enough insulation rating (certainly better than the current situation), but I wonder that if you shortened the resistor leads also, if they'd be more mechanically sound.

Good point Lew.
because there are so many loose ends there (32, if I count right), but the peace of mind will be worth it.
Better than fixing a fried amp.
