Paul,

Would you believe, some guy beat me to it with this design...

http://www.scopeboy.com/tesla/tc2schem.html

His is almost identical, except for cosmetic details.  It just goes to show 
that great minds think alike

Diode=12*5407 (in series) -I'm now going to use eq resistors and snubbers.

Capacitor C1=1.3uf microwave cap - 2500Vac

Capacitor C2-5 1.3uF in series/parallel - 5000Vac 1.3uF

Inductors approx 10H, using 26 AWG, probably about 12" long each.

I've just placed an order for the extra components - More diodes - fried 
all existing ones...  MMC pulse caps.  Just need the 26AWG for the 
inductors and secondary....

Thanks

Chris
