Dischargeing Lytics through a gap (Or BES Switch) causes them to ring back 
and forth as the power surges one way, then back. It's VERY hard on the 
caps, we have yet to have a failure though and we have over 100 Bangs on 
this system so far. This is Pulse duty though, not Tesla Ducy. This setup 
(even if properly set up for voltage) wouldn't last 5 minutes in Tesla Duty 
where the caps charge and discharge over 100 times a second. If the ESR 
didn't eat all the power, the other losses and inferior insulation/corona 
protection would put the caps into some form of catastrophic failure (most 
likely spark and ooze but explosions are very possible) in a few seconds.

Thumper is currently 80 caps, each rated 450VDC 2000uF all wired in 
paralell. It sounds like a shotgun going off and can be heard a block away.
