You got it!
I was wrong about which capacitor was hot. It was actually the cathode bypass across the 470 ohm resistor that burnt up previously. I've replaced that and have had the set running for about 15 minutes with no signs of any smoke or overheating. The main supply voltages look good too. I checked all the resistances using the Sams reference. They're all good. Now that the set seems stable, I'll check all the other voltages too.
No picture. I'm getting about 9kV at the CRT. It should be more like 14kV. I tweaked the hor. drive, size, linearity etc. but no change.
Also, no sound at all
I need to take a break and go pick up a new toy. More later.
