New update - I got some time to check components in the color circuits. Film capacitors and out of spec resistors all got replaced. There were a few resistors over 30+% but I suspect the issue was an open resistor that connected +275v to part of the 3.58 osc circuit. Other work included replacing the circuit breaker with a fuse and wiring in a bucking transformer to bring the line voltage down.
I picked up a RF modulator so I could connect a DVD player. With some basic adjustment I was able to get the picture reasonably centered, not much for color as I previously noted the CRT is weak. I continued to monitor the horizontal output tube current, I was able to get it down to a steady 210ma.
Next up:
- Swap out CRT, and make applicable adjustments
- Clean tuner, it seemed like I could maybe get a bit better picture and sound as I adjusted the fine tuning
- Figure out what is causing the visible retrace lines
