I was a bit confused by when you said '#Voltage at H Out anode cap is 140 “
That 258v there is normal and enough for it to work.
Next thing to look into is, why did you see a g1 voltage that was 1v too low?
Bad 5GH8A?
These go bad a LOT, you can try to swap with the one in v3 to see if that changes anything if you do not have a spare.
Also, this set dos something weird with the cathode of the HOT and has it wired to the circuit breaker.
You could try to tie it directly to ground for a bit, to see if that makes any difference, the breaker may be bad and not grounding the cathode enough.
