[TCML] DRSSTC and targets to strike

Bart, For this reason I used 0.1uF capacitors on the bridge and ground, to help prevent issues if my primary gets hit.  Followed this diagram:

I also used a bead on the GDT as suggested in the diagram, which did clean up scope waveforms.  Maybe steve can shed some light here, but if I'm not mistaken, it allows a streamer to hit your primary without things exploding.  I beleive this was how steve made his coils where you can see just a primary, and streamers hit the thing without it caring at all.
