if you don't want to do a recap, at bare minimum replace the coupling cap going to G1 of the H out tube. Then he sed the same thing.
The slightest leakage in that cap will push the grid more positive.

Yup.... There's 2 votes fer checkin the bias on the Horiz. Output tube....
Even if you decide to just change it, check the voltages first. It will possibly be
the only "test" of the cap, just in the small leakage there may be, even if any
possible cap. test itself may never reveal it to be bad, a higher G1 voltage may
be the perfect load test to show it's really bad....
