Hi Dave,

Very possible about the NST destruction, I did destroy an NST 
during all the testing with misfires, etc., before I bothered setting
up the scope.   I don't think the PFC cap is a factor since I'm not 
using one.  My guess would be that the NST shunt behavior 
"changes" as the power is raised, requiring a different phase 
position.  Actually I think it happens in PT powered systems too,
so it seems to be a normal part of SRSG operation.  Some sort
of non-linearity in the system I guess.

Cheers,
John
