Thank you for sharing your circuit. Looks nice, and interesting. Also appears to light the florescent tube very bright. Brighter than my circuit is able to do on 4 to 5 volts. There is a good video on YouTube about such a coil, actually it is two of the monitor tube ferrite coils that are wound, with one coil fitting inside of the other. They slide in and out for additional tuning. Your picture reminded me of that video, if I can find it again, I'll upload it.
Thanks for keeping this thread going, it's a shame that more people aren't interested.
