I don't see how the gap setting is derived from the power supply current
rating.  I would think that it is voltage-dependant, not
current-dependant.  Rather, I would think the current rating would
dictate the required "beefyness" of the gaps, how much heat it must
dissipate, while the voltage rating would dictate the gap spacing.  I
know that for my 15KV/30mA coil, that going from 5 to 10 gaps of .03"
each, made a world of difference in performance.  The suggested gap of
.045 sounds way too short, IMO.
