Twin coils - PSpice model development

["Tesla list" <tesla-at-pupman-dot-com>]

To all of you that have built a twin coil system:

I'd like to get a good PSpice model developed for twins.  Have any of you 
done measurements of resonant frequencies while the secondaries are not 
arcing together vs. when they are arcing together?  I haven't been able to 
capture much on a scope to develop a good theory.  Anyone have a spectrum 
analyzer I could borrow?

 >From my observations with my Twins, I think the secondaries operate at 
multiple frequencies depending on coupling to closest primary, coupling to 
other secondary, and whether or not the arcs connect between secondaries.

We're building a set of twins (code named Gemini) at The Geek Group.  You
