hi bart i worked out the time between bangs to be 2.5ms well the rise time
of my arcotronics caps is 1800v/us so this gives plenty of time to charge
one but how does this figure change with an mmc? i assume it will take a sum
of the 40caps to charge making still plenty of time
im no expert on this and would appreciate correcting
many thanks
