Thanks for the explanation on a very interesting subject (for which
I didn´t have an "instant explanation"). However, this can only
happen, if the experiment is conducted the way Richie did it. In
coiling use (aka: everything in the tank circuit connected correctly),
this can´t happen. The moment you shut down the power, all energy
will be drained from the inductor. Either in from of a last "cough"
of the spark gap or as energy stored in the cap. I.e.: the main
xformer is not shorted at this time (unless your main or safety gap
experiences a meltdown). So in "normal" coiling operation I wouldn´t
consider this a true danger. The (maybe) still charged primary cap
should be considered the most lethal part of the coil setup.
