Interesting point. I'm intrigued. But what about the first few hundred
turns or so on the neon transformer. Do you think that they will see a
good deal of RF? I'd like to hear more of this idea. I've never tried to
run a neon without a choke. Perhaps others hear have run neons extensively
without chokes and could give some input.
