This all sounds very interesting! It goes along with what Tesla said
about the primary cap acting like a "slack spring" if the capacitance is too
large. It would seem that as long as one can supply a high enough voltage
to the primary circuit, without suffering too much corona loss, this would
indeed improve the output. It seems as though modern coiling has evolved in
the direction of limiting the primary voltage due to the corona loss
difficulties and to the availability of 15kV neons.
This could cause a new direction for coiling! I can see the advantages
of the higher primary current from the higher primary voltage and wider total
gap spacing for quenching. I cannot wait to try out a new configuration
of my primary cap by placing them in series(.0125 uF at 80kVAC) instead of
their present parallel configuration(.05uF at 40kVAC). Although the max
energy stored will be the same , I have not been using an input of more than
15kV(neon). I think it is time to try out my high voltage
transformer(possibly goes as high a 70kV - haven't measured this yet).
Thanks for making us think!!!
