Hello Ed,

	When I did some measurements on this a few months ago, I and others found
that the high frequency impedance looking into the neon secondary was
considerably lower than would be predicted by a 500Henry inductance.
500Henrys might be ok to use if it is shunted by some effective internal
capacitance and resistance. Otherwise your spice numbers will not come out
right. No?
