Recap the motherboard.

Also the se30 board would have slid right into the SE so you could have tested it that way.

Do a search SE30's are some of the worst for cap goo and battery leakage damage.

Capacitors leak, rot traces and the goo is conductive so it causes even more issues.

Yeah, uni has already capped the mobo. It's been working fine. I'm just putting in a better analog board and tube now.

I'll check the yoke and the deflection cable- that is the red cable right?

The tube is from one system, the analog board is from another- it's all going together into the SE/30 case so that is where I am putting this together.
