Also the yoke wiring was disintegrating so I rewired it using super flexible silcone insulated wiring. The original horizontal yoke wires had thinker insulation so I assumed they needed something in the 1-3 kV range. After searching around, I went with test lead wire.
Unfortunately, shortly after reassembly I was having screen fade issues. I could smell something getting hot and assumed I had made a wiring mistake. While trouble shooting the circuit breaker in my PR57 popped. Finally noticed it was the power transformer that was roasting! Something shorted out inside. I tried to get water out when I washed down the chassis and baked it in the oven for a while. So who knows? Might have been moister. Might have just been its time. Luckily, I had a spare handy.

Back in business. Have sound now too after tweaking the coils a bit.
Shame about the very visible burn line.
