Mark,

I remember building voltage doubler and tripler circuits when I was in the
electronics business.  Like needing to produce 12v or 28v when only 5v was
available.  We always had difficulty producing much current from this type of
system - using only diodes and capacitors v.s. transformers.  Since Tesla
coils need quite a bit of current to get fast charge times on the primary
tank capacitor, how do you resolve this problem?

How much current are you able to get out of your high voltage doubler
circuits?
