The service manual from WG says B+ tp 202 should be around 117.4V

I measured mine and it read about 122.5V, is my B+ high enough to warrant me de-soldering and installing a new pot to adjust back to 117.4V ?

I am actually getting a slight hula with the picture too, is the excessive B+ the culprit?

thanks
 
that might be just high enough to trigger the HV shutdown actually. so yeah, I'd say it's worth it lol
 
I'd check the 33UFD and 100UFD caps on the B+ line ....pretty sure you have one, or both of these leaking causing your hula issue. Replace then test your B+ level again.
