Here is one my buddy found. I am fixing if for him, incomplete vert and lack of solid color sync, low contrast.
CTC 21 combo with the worst looking CRT I have seen big time mold (brown gunk). CRT test weak on two guns, but have not tried zapping it yet.
has power tuning that works, UHF tuner is gunked up, stereo sounds find has 4 big output transistors. Needs controls cleaned.
I think the vert problem was a corroded B+ line that was feeding the vert output tranny the electrolytic bypass cap was fine (as were most of the caps).
I did notice a green corroded filament wire that was on top of a pcb on the chroma board. I dont know if that could be an issue but I will go ahead and replace it. I suppose it could cause enough of a voltage drop that the tubes may have lower then normal emisson.
