Ok, I temp tested the coil, and it helped a lot, though I've still got a slight drive line issue - I'll have to adjust it and see if that helps (the width was way too low, I haven't installed the coil yet premenantly, so I couldn't adjust it).

The HV is now an 'exciting' 19kv at min brightness, and 17 or so at max. There's still blooming slight but you can adjust focus to stay good.

I'll play with it next week - this week I can't get to the set because I've got a field call in Puerto Rico, which is going to last all week.

Ok, with the coil in place, I've got exciting HV, plus I've got a drive line

A bit of investigating, and I found out something - the vertical lin control is a replacement. I know it is - on a closer look, it doesn't even fit right - it's too small for the hole. It's also 2X the DC resistance of the listed one.

So, it looks like that was replaced at some time. And the flyback.

I'm wondering if this set even worked right when it was shelved last. Maybe it had the drive line for a long time before the yoke (origional!) died. Why? Maybe it wasn't repaired right, maybe it was a 2nd TV, maybe it was 3 hours before the big game and the owner wanted a picture, no matter how bad...

Anyway, it looks like the horizontal section blew up at one time. With the right width control in, the width works right. The flyback's working right, I've got great HV, I can focus and there's good brightness.

I still have this drive line and it's smaller friend to the left. I think it's the lin control, it's just not the right one. If not? Hell if I know - maybe this set's cursed...
