Steve,

Looks like you have some real fun stuff going on there.  I would like to 
clone your little Marx Generator sometime soon.  I've wanted to set one up 
in my laboratory for a couple years now, just haven't gotten around to 
finding the caps.  I have some nice Lexan I grabbed from the local plastic 
place's dumpster that would make a great display stand for a Marx bank your 
size or larger.  I may send you personal email to ask a few questions about 
where you got your caps, and a few other minor questions.  Keep up the good 
work!

-Brett

Ah, you see Dan, if you used a self-resonant design (just kidding, it would
not be easy to make a feedback based audio SSTC) , then many things are
possible, including the jaccob ladders ive built with my SSTCs.

For some cool experiments see this:

also, other experiments in the SSTC index:

have fun!
