Would you please post a recipe or detailed description or at least
point to the necessary data somewhere on the web so that I might look
at exactly what you are doing and accurately reproduce the machine
you mention? My ability to reproduce anything in the short term is
somewhat limited by a bunch of circumstances (active coiling has been
considerably curtailed since I got married for one thing) but I will
promise to make the effort.

I'm surprised that you do not consider the self-capacitance to be
relevant given that it is (in my opinion) inseparable from inductance
to whit: whenever there is a current flow, there is inductance and
where a potential difference is present, capacitance, both being
present in an operating Tesla resonator.
