[TCML] Tesla Coil Tuning
Recently i installed an asynchronous rotating spark gap on my coil and
its breaks rate is 1,100 bps (and it does fire continuously it stops
and goes). And i and puzzled as to why the performance of the coil
has not increased, it seems the same as when i used a static spark gap.
I am tapped into the primary at 8.23 turns, because its where i find
the streams are the best. However that being said the longest i can
get is a 8".
Here are the specs for the coil, i used TeslaMap5. Any insight would
be appreciated.
