Fada Restoration Gone Wrong

About a month ago I started my Fada restoration project and everything went very well up until the other day. This is a Fada model 21T, the CRT is a 21EP4. All the electrolytic and paper caps have been replaced. I checked the wires and resistors, everything seemed ok, so I went ahead with a slow start. The set came right up with sound, then I was greeted with a nice bright test pattern. Then I cleaned up the cabinet with a new finish and started to put everything back together. After all that I noticed the image on the screen was tilted a little bit. What should of been a simple adjustment to the yoke turned out to be a nightmare. The Insulator between the deflection yoke and focus magnet was wasting away more in the center area than it was around the outside area exposing a solder joint with the back of the focus magnet. Needless to say as soon as I put my hand on the thing I was greeted with a spark and insulator pieces went everywhere. After quickly cutting power off to the set, I took the focus magnet off and saw what had happened. At that point I thought, maybe everything would be ok but i needed some type of insulator. I took the cover off of a blue storage tote lid and made an insulator, powered the set up and O crap what did I do. The image on the screen is all screwed up. At first there was no light on the screen, as a result the ion trap has to be right against the focus magnet. Not where it was before this happened. The left side of the screen is completely dark with an off center image. Rotating the yoke has little or no effect on the left side off the screen. (second pic below is before this happened) I hope someone can shed some light on this problem and point in the right direction. but I think i might have damaged the crt as the yoke seems to be working.
