   Right, but I'm still fooling around with flat secondaries, hence my 
question. Your O.P was about secondaries in general and a few regulars here 
have done some work with flat spirals. I was wondering if anybody'd tried 
to find a "Freau Equation" for them.

   I'm working less than 100W total (but spark length is dubious due to 
coupling problems and driver circuit fires) so a few more data points would 
be helpful. ;>)
