Yup... and that is what I will do.  But I do have some questions dealing
with the permeability of the core, and if it is gapped.   I should be able
to spot this in the leakage inductance though.  But the true magic is in how
they can sustain 12Kv without being vacuum potted.

I would really love to talk to the manufacturer.....
