The picture at this point is excellent aside from some ghosting (and that I can tell it is not from an excessively strong signal). The concern is that there is little to no width control and even on the pattern generator I can't make things fit so we're looking at an image that is around two inches too wide. I don't recall moving the yoke that far when I reinstalled the tube. Just a light adjustment to center the picture again.
I'm not running with an isolation transformer. With my knowledge of bakelite we should not be seeing a voltage being passed through the insulated socket at all (especially with these "low" voltages). If I knew where to source a replacement I'd try swapping it out. I've already zapped myself on this set several times because of it but nothing ever warned that this was a hot chassis. It raises a flag IMHO.
I'm not hanging my scopes off this until we sort this voltage issue out. If you want to look at the schematics yourself I posted them back on the first or second page
but here's a high-res version if you want to be able to read anything.
