I'd suggest using the Duncan PSU designer prog. to model your PSU and get a
figure for the rms (=heating) current in the caps. Then use a low voltage
transformer and variac to get that much current through the caps and see how
much they heat up.


PS There's an updated version of the prog as of yesterday changed so that
the prefix for kilo is now correctly lower case.
