The problem here is that neon bulb relaxation oscillators top out
at, according to the charts in the book, at between 10 and 30 kilohertz,
depending on bulb type.

I was curious if there was a limit on the upper frequency, and I was
wondering
about the waveform as well; that is if the circuit can produce strong
harmonics
up into the upper HF regions. It would be an interesting project to build!
