I have a 20ez in my Mario bros that has been working for years but one day it started to pulse and wave. I thought it was the B+ cap so I changed so and it solved the pulsing issue but the image is smaller than it should be and the b+ is low at 80v and it's not adjustable. So I replaced the B+ pot and flyback and that did not make a change. Is the voltage regulator bad??
