The answers I have heard are a resounding 'NO'. These caps aren't designed or
intended for the level of ripple current that you get in an amplifiers PSU, and
they fail fairly quickly. Usually killing other parts in the process. The
fairly big paper caps intended for SCR commutation should be OK, though.

Subject: [Amps] Filter Cap. question
Working on a new amp project here.
In the past, I've always used banks of 8 or 10 aluminum electrolytics
for the HV PS filter, and they have always worked fine and lasted
quite a long while.
Lately, I've been seeing caps of the "energy discharge" variety that
have been removed from cardiac defibrillators. Is there any reason
these wouldn't make good filter caps in the HV PS of an amateur
amp? Has anyone on this list had any experience using them for that purpose?
I always considered the big can oil-filled caps the "gold standard"
for filter caps, but usually I wasn't able to get my hands on them to
use. Might these "energy discharge" caps be just as good?
