Well I found the problem with the width. When I had reinstalled the HV cage and something arched, a couple of mica caps had shorted in the hoirz osc circuit. I replaced the mica caps on both the plate and grid of the 6SN7 horiz osc and not have good width.
However, the original problem was still there. Every time I would try to reinstall the HV cage, I will get a wide black bar across the screen and something starts burning under the chassis. I couldn't see anything under the HV sub chassis that would be arching to the cage, but I coated all joints with HV Corona dope. Finally I decided to try to place the cage on with the set running. I then noticed some arching from the flyback coils to the cage.
I coated all the flyback coils with corona dope and was finally able to install the cage.
However, after I got the width fixed, I noticed I now have 2 vertical half frames, so I'll start checking voltages on the vertical circuit next.
