OK -- I'm still a bit confused here, so . . .

OK, so remembering my basic power supply knowledge, it's the PRV of the
diode that determines the output voltage.

Does this mean that the 19V2000 needs a DIFFERENT diode, to make the 14.5kv
instead of 12kV ? As in, SK7333 is actually wrong, since it crosses to H1812
instead of H1809 ?

Mouser lists some general, high-voltage rectifiers. In the .35 amp range, we
have

        PRV IFM (Surge A)
HVM14 14000 50
HVM16 16000 50

Would one of those do ? If I understand what you are saying the PRV value
has to be within +- 300V of 14.5kV ?
