Hi,
I'm trying to produce a good flame from one of those tube oscillators running at ~20-50 MHz, but so far haven't succeeded. I don't want to use that base fed oscillator with an "antenna" near the output, as it seems kind of unpredictable to me, and a single arc-over can ruin the tube. I'm fine with the base fed concept though.

Anyone got experience with those? Are there any circuit concepts which seem to run reliably?
