I can really relate to your perdicament, but I can't help you exactly
as requested. I have a comment. A capacitor size of 0.05 mfd is
rather large to fulfill merely a three foot streamer requirement.
I've just posted jpeg pictures with the generous help of Jim Fosse on his
ftp.bdt-dot-com/home/jim.fosse as xxxxxrws.jpg files. Check out
ltc04rws.jpg Here I blast an 18 footer from a 0.05 mfd cap charged
from a 16 KV pole transformer. While you're there check out my
stc01rws.jpg This is a 60 MA, 15000 volt neon powered coil that
consistently punches 40 to 52 inch streamers depending on humidity.
The capacitor is only 0.008 mfd!, a bank of 30 pieces of 0.002 mfd,
12400 volt peak, mica's in 3 parallel groups in series for a peak
voltage rating of 37,120 volts or so.
If you can't find the big commercial caps you initially looked for, don't
overlook mica transmitting caps that you might find locally in
surplus stores. In fact a case of 12 beer bottles filled with salt
water in a salt water bath all sitting inside a plastic tub with an
interlinking wire dipping into all the bottles as one terminal, and a
chunk of wire immersed in the tub as the other terminal would also
work in a pinch. This is in fact exactly the type of capacitors that Nikola
Tesla himself used at Colorado Springs, and look how famous these
made him! If this setup doesn't look professional enough, hide the
array inside an outer housing with impresssive technical markings.
I'd be happy to share some of my secrets if it will help you out. I
know this is an important 'gig' for you! I'm in Ontario, Canada, and
that's probably too far from you to send anything fast enough that
will really help except maybe technical tips.
Hope this helps.
Happy coiling!, rwstephens
