Well, I've returned from Yo So Mighty park. Last night I powered up my
new system. I was trying to recreate John Freau's 65" arc from a 15KV
60 neon. I was only able to achieve 50" with static gaps;( I then made
the mistake of adding my async rotary in series with my static gap and
blew something. I'll post mortem the system later today.
cheers,
