Must be a common issue on this set. Good to see how all the stuff on the rear of the picture tube is set, though.

From what I've read, this chassis has a vertical integrator like alot of the early 60's B&W Zeniths had. I'm betting that's the problem. First I want to get the color working.
Does anyone have a schematic for a 25MC33 chassis by chance?

PS the chassis shelf is flimsy; be careful not to rip off the back side of that groove that helps hold the back on.

Thanks for the tips. I was wondering what that fishing line stuff was, and I would have never guessed that the height/lin controls were hidden like that. Good thing I left those strands of 10lb test alone. I'll swap out the tubes in the color section tomorrow.
I can definitely see what you mean about the cabinet shelf. The chipboard is, well, starting to shed chips, mostly from the bottom. I was wondering if I could brush a coat of heavy duty polyurethane on the chassis shelf to control the problem?
