Malcolm,

I don't think that close rotary electrode spacing would reduce the Ep, 
since time = voltage (up to a point) in a rotary, so I would favor your
second suggestion.

Still intriquing, esp. considering your theory about the RF rate feeding
of the sparks.

Your work and your approach to TCs is alway interesting,

Good luck with your tranny rebuilding.  The trannies I have here don't 
seem to have a lot of extra room available for larger wire sizes to be
used, and pie winding may waste some space.  Maybe your tranny
has more room available.
