Malcolm,  all,

I suspected it had to be something of this sort.  I'm glad to hear
there is theoretical support for this degree of build up.  I verified my 
scope readings using the safety gaps, and everything agrees.  I've 
posted that separately.  This may complicate the calcs of those
who are not monitoring their actual cap voltages in their sync gap
systems.

Thanks,
