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. =)
