Little background on this set. I didn't do the resto, I got the chassis this way in a swap and put it into my table model porthole cabinet. Just about everything conceivable was replaced. Yoke, fly, resistors, caps, etc. All the correct parts. It's been looked at by a couple of the best TV minds I know, and nobody can puzzle this one out. It'll run for hours and be fine, basically just like this. Transformer is nice and cool as well.
This is a very weird chassis design. Half series string, half transformer. The top of the chassis is hot, but the sides aren't....they are insulated from the top by grommets and wafers.
That said, I'll be okay with a "kludge" if it works
