CSI is based here in California. I aquired the caps from an individual who
worked for CSI. The company
I was working for in MN bought large quantities of pulse caps for flash
tubes (toner fusing on high
volume check printing equipment). Because of that, they kept us happy. I
talked to a guy at CSI about
TC's and was looking to buy caps appropriate for my system. The guy said he
had a few of these 60kv
caps lying on a shelf for quite a while and would send them to me (no
charge). Obvisously, I was
amazed and quite the happy coiler. I later found out I was sent a few
thousand dallars in caps. This
individual knew about Tesla Coils from a bad experience. Someone from Texas
had a custom cap made.
When it failed (due to lack of experience by the coiler), daddy had it out
with CSI. Because of this,
I haven't made CSI real well known. It only takes one coiler to ruin it for
the rest of us.

Anyway, I've since lost contact with CSI and not sure of a web address. You
might try looking around
the net. I do know the guy who sent me the caps is no longer with CSI (no
more free stuff for me). I
actually gave two 0.01uF caps to a buddy at work. I may contact him tomorow
to see if the company
still deals with CSI and see if he isn't using the caps. Maybe I can get
the two caps from him. That
will put me in the 0.08uF range for my coil. <big grin>. Then, my big coil
and David Reiben will be
nearly identical. (two good running sonotube coils).

If I can find out more about CSI after my call, I'll post back whatever I
find out.

Here's what info for CSI that I have at this time:
