Hi
This is probrably the tube but you need to check the base voltages first.
Do the A1 pots alter anything - i.e. make the picture even darker?
If they do then I would suspect the tube at this stage and you need to check it next.

PS: I have never known an IC to fail, but these are a few years older now.
