HELLO EVERYONE: After two years, working a little at a time on the 24H21 chassis, I have gotton this far with I (see pic) horz and vert are in place, as far as the controls go, but having a over lapping picture/xmas tree effect problems, any suggestions would be greatly appreciated. thanks, chip:scratch2:

I'm leaning towards part of your problem being the horz osc is way off. I had a set that looked somewhat liked that, and after adjusting the osc slug several turns, the picture became 3, then 2, then one. Looks like you have 4 going there.

If you try that, remember how many turns you give the slug... just in case I'm wrong... so you can put it back the way you had it before.

Thats pretty much an adjustment as posted above, i kept turning untill the horizontal lines got thicker if they get thinner then yer goin the wrong way

Like they said above this is a misadjusted Horizontal Frequency, it's not the regular user adjustment though, it's probably a coil with a slug somewhere on the back apron or on the chassis near the HV cage.
