I got several used tin can capacitors, 40 uF @ 3 kV, about 8 pounds each,
probably film in oil. With such capacitors, is there any potential problem
if I do not keep them upright during operation?? Normally I would assume
that wouldn't be an issue, but I've never used such heavy caps before, and
especially as they are old with a few small dents on the casings, I'm
worried whether stuff may shift inside if I work them horiziontally.
