UPDATE: It works! I removed the brightener, checked the CRT on my B&K 470 and it tested good-to-very-good! So I variac'ed it up over about a half hour, cans stayed cold, and I started hearing the horizontal osciallator at about 90v on the Variac
High Voltage crackled to life, and I got a nice raster. So I hooked it to cable, and here came a decent picture. I had to spray the tuner (YES, I know that's the wrong way), and it seems quite good. May have a few bad caps in the IF circuit, or maybe a weak tube in the front end. Has a beat pattern that you can't get rid of without getting rid of the color too. Also has a focus problem, hopefully a faulty 2AV2. This is a low-hour set, I think, because the tube diagram is still in good shape and they usually get brown & brittle with heat of usage.
Anway, I stuffed in a hole in the livingroom...
