Ordered a few parts to see if I can fix it.

Did a cap kit from Ian Kellogg, and the vertical deflection transistors Q401 and Q402. Did you find the manual for this monitor yet? Just got mine partially working this evening.

I got mine working mostly. B+ voltage still high (116vdc should be 105vdc) and causing some vertical instability issues.
