@ist, look forward to any new pictures of your circuits in action!

..hehe, we're on the Pi page now.  Aww... atleast, we were on the Pi page.  Can someone clarify for me the reasoning behind bridging the terminals with a cap in this diagram?

I don't see what the point is.  If there is a newer diagram available, please link me to it.

Electronics goldmine has them 1" OD x 1/2" thick....5 for $1.00.  Very good price.  That is where I got most of mine.

Great job tuning you toroid, so you say 76 volts dc for each pickup coil ? so 4 time 76volts dc . maybe a 2n3055 could get you close to 100 volts.

Great!

I think the proverbial box is broken !
