ive noticed when your resonant circuit set up like: pulsing electrons out of a capacitor,,, into opposingly wired dual coil inductor,, and into ground,, then choke will restrict amp flow
higher inductance henries value seems to further oppose currant .
when you insert the neon tube before the ground then look on oscilliscope and see even higher voltage at point of beginning of choke.
so when you have 2 coils of wire ie. like on a transformer you can connect the 2 windings 2 different ways. one way give higher henries.
do you know the inductive value of you chokes kickbackemf ? i have a few small plug in wall transformers which range from about 1 - 3 henries when they are wired correctly
