Javatc recommends .027 uF (2.7x resonant) for a 8750v/35 mA with a 120 bps
synch rotary (using .0165 now, trying to get longer or at least fatter
sparks). Does this sound right or did I screw up somewhere? I thought 2x
res. was usually the upper limit for caps before they didn't charge enough
before the next break.
