I'll add my congratulations to the rest!  Good work, Terry.  

One thing that surprises me, not having to do with the primary scheme at
all, is the spacing you have between the top of the coil and the toroid. 
I would have thought that the field of the toroid, "protecting", so to
speak, the top of the coil, would not extend that far.  I'd expect sparks
from the top of the coil.

Let me remark that your work with the OLTC has inspired me to consider a
lower-resistance configuration in my s.s. system, in order to improve the
amperes-x-turns factor toward what you have achieved--and to bring it
closer to what I had had in mind in the first place.  After all, it's
ampere-turns that do the job in the primary, isn't that right?  I'll post
something shortly for those interested in a possible adaptation of your
fundamental notion--low voltage applied to a very-low-impedance primary
coil--incorporating my current s.s. scheme.

Jimmy Hynes' comment about "k" is interesting:  I see nothing except
dielectric breakdown that would preclude making k as high as possible, in
a s.s. system, as long as the driving transistors are protected against
voltage transients.  (I'll try to work on that...)
