Steve,

This is a very impressive power vs spark length ratio! I
may have to consider giving up on the pig coils and try
to build one of these SSTC  coils to get that kind of
performance. I fear that I, like some of the others have
mentioned, am too unfamiliar w/ solid state electronics
to comfortably take on building a SSCT of this magnitude. I know that IGBTs
of this magnitude don't
come cheap if you fry one or two of them in the learning
process :^O

BTW, are these 10 ft streamers as loud as equivalent 10
ft streamers from a pig driven coil pulling around 7 to 8
kVA? I figure that they probably aren't just because the
absence of a SG if for no other reason.
