Possibly a sweep-derived voltage serving the video stages also.
If somebody could post a schematic of CRT and G2-video circuits, we could pick it out.

I have a PDF of the schematics. It has all the boards, part lists and circuit diagrams. Only problem is that it is too large to attach here. Which boards are you needing? Is it the video output board (9-121)? That's the board attached to the neck of the CRT. It has the master G2 and the RGB G2s. If that's the board, I might be able to copy and past that info into another smaller file.
