Better than that. I’ve seen setups like this.

Thanks! Fun stuff.
Thinking about building one myself. Looks pretty straight forward but there are some nuances. Plus, you are working with some very high voltages (the line transformer secondary).
Interesting too that you can drive the oscillating circuit with a transistor. Must be a very high voltage transistor. That is how you get the music.
There are several plans.
Also, I have seen them and they are loud! And they generate a bunch of RF energy and noise which can really mess up nearby electronics. I wonder if my neighbors would appreciate it.
