Typical diode strings have a 50% to 150% safety factor. According to my
tests, 450WVDC-rated electrolytic capacitors are in Very serious trouble
at 25% over-voltage.
It does not seem likely to me that a lightning strike could: 1. destroy
the HV transformer. - - 2. destroy the diodes - - ... and yet not
damage the HV electrolytic filter capacitors. OTOH, I have heard of a
number of cases where a HV arc somehow managed to do the hat trick.
