Singing hot plasma using a simple circuit 🎵🎶

This is a simple Class A amplifier using a single MOSFET that modulates the input supply with audible frequency. That's pretty much it.

This is really impressive. Can you provide the PDF with the complete circuit?

Sorry, but I don't have a PDF on this circuit. This is the circuit itself at 0:26. It's basically a Class A amplifier that's modified a bit, which the Transistor (MOSFET or BJT) goes in series with the positive supply. I learned this circuit from Electroboom's "DIY Arc speaker (AM demodulator)" video. ua-cam.com/video/eyVDMJN0sa8/v-deo.htmlsi=xNpPJbhAgMrB7B2N
