Hi Malcolm,

I think the safety gaps are telling me that the voltage is higher with
the .0077uF than with the .0147uF for the same input power, and
same spark length, as would be expected.  I guess the bang sizes
must be about equal.  I didn't actually measure with scope and HV
probe.  I agree the LTRS cap should stress the NST less than the
matched arrangement
