I did notice the similarity when I visited your site, and I recall making a
few in-process changes based in your success (thanks).

Sorry about that, I've been using "LED" incorrectly as a "catch-all" lately
it seems... it's actually a neon bulb with a green plastic filter over it.
I'm really curious why it flickers still though :)

I purposely kept my secondary high (primary low in my case) because I didn't
want to have to endure the stress of maybe seeing my secondary damaged on my
first run (not sure how likely that is, but just in case)
It is very easy for me to adjust. ... but I'm not sure I know how to tell
when it's optimum........ should I go to the point of "racing sparks" and
then reduce the coupling a little?
Thanks a lot for (all) of your input.
btw, Gary, I have to say that your photo at
