Guys, I've been running my 2 rolled caps at 12kv for close to a year
without a burnout. The first one I ran alone for about 9 months.
That cap sat in oil for about 2 months or more before I ever used it.
The second one sat for at least a month, but was hooked up in series
with the first when it was first fired. Do you think that the oil
saturating the roll is preventing a burnout?
Of course I am using the 2 rolled caps for a stand for the primary now
that I have my 2 commercial caps. :)
