A few years ago I reversed the PM3320A PSU. I still have the
schematics, but looking at it I didn't completly finished the work.
AFAIR it finally was the EHT transistor that was fried and made the
main PSU have vapors.

The 3320 and 3323 share a lot and almost surely have identical
supplies. Even if the schematics isn't completly finished (maybe up to
95%), it'll be useful.
I send you a copy.

JUNK is stuff that you keep for 20 years,
then throw away a week before you need it.
