[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?
