Video Problem need help

[ohohyodafarted]

Thanks John for the tips. The set was totally recaped including rebuilding the cans, so I think it is not so likely the problem would be there, unless I got a bad cap from my supplier.

I will check tubes and see if I can find something.

Checking the tubes may not show heater-cathode leakage. I would check by substitution if possible.
