Well, I was able to devise a method to get the chassis powered up and in a position where I can work on the underside. I traced the video path with my scope. It disappeared at the 1st video amp 6v6. During my work I inadvertently lifted the grounded side of the filament ckt at the 6v6. (this is the kind of dumb stuff you do while working at 4AM when you should be sleeping) Video is now back with the video image shifted by 1/2 screen and the vertical bar in the center is still there.

Next step is to use my scope with the info that Kevin Kuehn posted and see what my scope discovers. Hopefully this will lead to discovering the problem.
