First cap replaced!
Changed the CRT bias control (melted a long time ago), set the screens, drives etc back up and let it run for an hour.
Replaced the coupling to the video output grid. Weird!!! The brightness control had a delayed effect and the picture was slightly smeary. Checked the original, it was perfect! On value and no leakage! Pulled the Solen, checked it. It was supposed to be .1 mfd. It was a whopping .51 mfd. This threw the brightness control a new one as it biases off a 3.3 meg/330K ohm network. Took too long to charge from the cap being way too large.
Got curious. Put a high voltage (1200 volt safety cap) in it's place. I can't see a difference yet. Operation is normal again though. I'll try some in the color circuits next.
