Carl,

I forgot to mention too, but some of my coils cannot produce the
straight swordlike spark no matter what I do.  It must be a combo
of the coil shape, tuning and osc. characteristics, feedback, coil
Q, etc.  I'm not sure what coil parameters are most important to
the effect.  I posted more about the horizontal sparks in another
posting today.
