That subject has popped up on this list on several occasions. By
dividing the dc voltage by two is in the safe range to keep a
dc rated capacitor alive in tesla work.
Of course it also depends on what type of dielectric is in the cap.
Mica is the best materials for a cap used in tesla work
and should handle half the dc voltage and probably a bit more quite well.
Those WW2 caps are not only great caps for tesla work but also quite
some museum artefacts and it would be a shame if they were destroyed.
Hmmm, my two cents worth of personal thinking. I seem to get nostalgic
everytime i get around vintage electronics. =)
