Are you saying the picture is not linear horizontally....? That could be a bad coil in yoke,
or a capacitor across the coil in the yoke, or a wave shape not right somewhere along the horiz section. But just for S's & G's turn the yoke and be sure the problem follows you turning the yoke, if yer worried about the tube and that mysterious blue thing causing the problem in the picture..... But if linearity is a problem, I would bet it's also causing HV issues....

If you got the Sams start doing voltage checks, resistance checks, and O'scope
checks, do the easy stuff first, voltage and resistance. It could show up doing any of those checks. Horiz Osc, Horiz Output, HV Transformer, Yoke, whatever they give you check it. I once went nuts tracking something and finally just did the resistance checks off the Sams and found it really fast, I felt silly for not doing it first.

So is the picture not linear horizontally..? Is it really bad..? Or is it pushed over to one side....??
How would you describe the picture...? Do you have a cross hatch you can put on the screen...? Does the horiz hold lock ok...? AGC set correctly...?

I would say then, that you might need to check some wave shapes with a scope to see
if the horiz osc is running right and with the right shape on the wave.... Right voltage on the wave too...

well the scope thing wont work because i dont have one. but if the horiz frequency was that far off then it would effect the hold i think and it locks fine.there are other things that i found when i got this set that i dont know why but it could have a bad flyback because something was done to this set that burned the 100k resistor in 2 on the focus coil and it may have heated the core windings in the fly that may have changed values in some way. i did do a comparison ohms on both the flyback and a nos one i have and they were within 15-20 of each other. the fly in there now was a new one from maybe early 80s.

Since you get a picture, I would say the frequency is on, but the shape of the wave, or
the shape of any part of the waves along the way in the osc. circuit may not be right, or the voltage, or height of the waves may not be right. If the picture is off center, then something is wrong osc, AGC, Horiz Output. I would begin with these based on your description.....

its not so much about the centering which i could live with its the hv i cant get up where it belongs, just touching 25kv reg cap off, crt cap off it will stay up there but put antenna on a pic is there scene changes and the hv will drop to 19kv. seems like the bias is up to far but its counter all the way, move it a spec to set up the guns and the hv drops way down, just is not right.
