Re: capacitor identification

great! thanks to all who replied to me about this cap!  i have been back
from my first year at college just about a week now and just got my coil
back into operation. what a wonderful feeling!  and i have been reading the
posts about how bad ozone is for ya, but in a strange way i missed smelling
it... cool, tesla coils are just too much fun.

later all
