A sync rotary gap (synchronous gap) uses a synchronous motor that has it's
shaft rotation synced with the AC line current. Thus, the gap will fire at a
predetermined point in the AC cycle. This is useful in that the gap can be set
to fire at the maximum voltage all the time and not fire at less than optimal
times. They can be very useful to get the best output from a coil.
