First, you wouldn't be raining on my parade! You'd be raining on
Malcolm's. Be that as it may, Robert, I am well aware of the
non-linearity of input power to spark length! The general guide for
small coils is around 300 watts per foot of spark. To correct you
Malcolm DID achieve 60 watts per foot for 4 inches or 1/3 of that
foot. The whole point is untill Malcolm's little coil the best I've
heard for a 4 inch discharge is about 100 watts. I a not saying that
Malcolm can put 60 watts in that coil and get a one foot discharge!
What I a saying is Malcolm seems to have broken the record on spark
length per watt for small coils!
