I agree that electrolytics need to go through a forming process when
they are new. I don't believe that they need occasional "re-forming"
however.
Do Not use audio hifi capacitors in your flash. Electrolytics designed
for photoflash use are specially designed to have very low discharge
resistance, so that they don't heat up as much on a full charge dump.
Audio capacitors are designed to have low distortion and a wide and
uniform bandwidth. They are different animals.
