Re: rotery for neons (whats a sink rotery)

to: Chris

Just a short handle, ie, nickname, for synchronous rotary spark gap, usually
1800 RPM with 4 electrodes firing on each peak of the AC sine wave.  Could
also be 3600 RPM with 2 electrodes (usually used on higher powered coils).
It's commonly called a synchro RSG  (not sink like in water sink).
