My nst experience with coils is along that of Dan's. I started thinking 
though, if I use an ltr capacitor, have my spark gap right across the 
transformer with fat solid wire connecting the output of the transformer to 
the spark gap, and I set my spark gap to .200", I should still have a set 
of safety gaps in parallel with the main gap? How will the safety gap do 
anything that the main gap can't do, since afterall, the main gap will fire 
once the voltage is above a certain level. What am I missing here?
