I feel dumb for posting this. I know there have been a dozen threads along this line over the last year.
But doggone it, I've got an EZ that won't get off 138V for B+. I've tried new IC601, Q901, and checked every component (including VR601) and trace in the 600s. I've tested the flyback using a ring tester...seems good.
Adjusting VR601 (or any of the pots on the entire chassis) has no effect whatsoever.
What next? Looking at the schematic, I don't see what else could be the problem? What am I missing?
