Greg,

I was thinking in terms of using just one capacitor bank and a regular
sync-gap...I didn't realize that 3 cap banks would be needed.  The 
sync-gap would have 6 electrodes instead of the normal 2, to handle
the 3 phase...am I missing something?  I seem to remember that
someone tried this (maybe Tesla?) and it worked well.

I agree with you about the ease of power throughput adjustments...that's 
one of the disadvantages of any sync-gap.
