Dear List,
With regard to recent discussions concerning whether or not resonant rise 
occurs in spark-gap excited TCs, is it not feasible that these do in fact 
exhibit such behavior -to a certain extent at least- due to the fact that 
the magnetic coupling between primary and secondary coils is not perfect, 
and the resulting "leakage" reactance (from the noncoupled flux) which 
exists in series with the "ideal" transformer (the coupled flux) could at 
least in theory be made to participate in series-resonance with the primary 
and secondary capacitors across the turns ratio of the  ideal transformer?

Jolyon.
