My motorola Has terrible focus

I've been working on restoring a 7VT5 that I picked up awhile ago from the original owner. Today I finally got the caps replaced and the chassis back together thanks to a parts chassis I had.

First light on the screen was WAY too bright. I quickly turned down the brightness. THere is poor contrast, and I have trouble at times keeping a picture on the screen. The sync is stable, and there is clear, but hushed sound.

The worst part is, the picture has terrible focus, even with the control maxed out. I don't really think its the picture tube. The raster was bright as hell when it first powered up.

What could be causing this bad focus problem?


**Some screenshots and the near finished chassis pictured below. Finishing touches will be a resistor network to replace the 'ballast tube', and new rectifiers.**
