I know. Once I get this thing tuned with that I'll move on to either
the RQ static or an RSG.

I found the RC filter on your web site. What wattage resistors would
you recommend for a 15/60 NST? You said you used 250W but that it was
overkill. Where can I find 30KV caps? I tried Digikey and couldn't
find anything. Also, what about a filter on the 120V side of the neon?

I've probably done something stupid. I'm off to give it another whirl.
