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. :)
