Einstein, do you own a oscilloscope where you could hook it up to positive high-voltage side of the Tesla coil oscilloscope using a old-fashioned CRT high voltage probe. Quite possibly you might be able to detect harmonics in the audio range. Just a suggestion. Should you decide to do that be very careful of the RF Burns or better yet, just hang the high-voltage probe without holding in your hand when testing.
I have been using a PC oscilloscope made by Picoscope for the past 15 years. I'm on my fourth one. I occasionally have accidents with the scope. Currently I'm down to two channels left on my 4-channel Picoscope. The advantage I like with the PC scope is you can use a large computer monitor to view the waveforms.
I did construct a couple of high voltage probes to use for monitoring the Tesla coil waveforms. But I never overcame the fear factor of actually trying to touch the Tesla coil electrode with the probe. But a while back I accidentally discovered that just an ordinary coil of wire would pick up the sine wave form being produced by the Tesla coil. It's much safer to use. And dirt cheap to make one. Just 10 turns of 20 gauge magnet wire at a 3 inch diameter is what I am currently using. Because this seemed like such a useful tool to have, I made a special coil form with its own dedicated scope lead to connect to my scope. I just happen to have a video of the pickup coil I made with the Tesla coil waveform being displayed on the computer monitor.
