Here's some photos of the inner workings

So after removing the chassis to inspect the wiring, and poking around a bit, then re-seating socketed transistors in the video section, the problem magically went away. I let it run for a while, and the interference which preceded the problem popped in and out a couple of times.

I am now suspecting either a bad solder, or perhaps a shorted wire or component lead. I will let it run longer, and see if I can narrow it down more... I think the issue is somewhere in the video amplifier.

Thank goodness I didnt begin this work with a bulk recap!
