I don't think its a tube though. I think radiotvnut hit it on the head with the 100 uf cap in the vertical section, but we shall see.

Since he needs work now, maybe he's a good candidate for the dc restoration project...

I think I confused you regarding the 100 uF cap. That was only used in the '80's GE solid state sets. On your set, I would check:
1. The vertical hold pot. It may be dirty or defective. I think GE had a problem with some of those pots failing.
2. Check / resolder all the connections in the vertical circuit.
3. Clean the tube socket for the vertical tube(s).
4. Check the caps in the vertical sync circuit.
