Width Problem with Capehart Model 320

[Mike3]

Hello .. this is my first post here .. I have a Capehart model 320 I have been restoring,, and have pretty much fixed all except a width problem.. the crt has a line on the left side... that is wider when you first turn it on and as it warms up 5-10 min the line gets smaller...but never goes away.. and if you try to adjust it out the picture fades and you loose contrast.. I am not a tv repairman.. but I do have a background of self taught electronics,, 30 some odd years,,
I have been posting my progress on the other site.. under capehart 320..the set has been recapped and all tube double checked.. so where should I look for this type problem...

Thanks.. Mike
