I'll be looking forward to that -- my HV supply is coming along nicely. With just a little tuning, it's drawing about 60ma off the fet rails, at 35v input (out of possible 160v). No load of course, but it makes nice arcs and nothing gets unhappy. So at this point, it's mailny getting it all packaged up.
We've tried various sparkplugs here, best so far was some hard to find ones from an old model Ford (A or T, not sure). The ones with R in them burn up too easy, and we've had some that leaked.
The ones I see in your picture look better than any we've used yet -- long on both ends, so easy to work with. Any numbers on those? Here, you can't just to in the auto parts store and look around to find things like that (the old time mom and pop stores are all gone) -- you have to know a number (or a car that uses them). Ones without an R are getting hard to find at all.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
