Could your control pots be going open, or the supplies driving them be feeding the wrong voltages?

EDIT: Should have refreshed the page before replying.

you must have the jumper in that's a given.

You should have good HV regulation. If not then you need do the HV setup which includes current checks of the 6bk4 and the 6JE6.

the next step on what to check will be dependent on the outcome of those checks. Stop worrying about the lines until the HV is working correctly.

I am not going to list the possible problems as its just a lot of speculation with out knowing the current in the regulation and horz out tubes. I don't believe in random attempts to solve a problem. there is a methodically approach diagnostics. You MUST have good HV regulation, after that you can move on to the next issue.
