I have no experience building an audio amp before but I have built a Tesla coil or two. I attached an image. Basically I want to build this video here
. It is a Tesla coil fed purely on essentially a class-D audio amp. It’s a hard project to do but I have built a Tesla coil before which I have attached. The idea of attaching an audio amp to the Tesla coil is to remove pretty much all of the audio distortions. I have been teaching myself audrino coding and I am in college with one of my subjects being alternating current so I know what formulas I will be using for design. I do not know the best guide for the design of a class-D audio amp. Ideally it would be single channel, simple to build and be capable of being scaled up to higher voltages. This topology can be scaled up infinitely. Ideally mine would be small, scalable, simple and highly efficient . As a noobie to class-D amps I do not want it to go further than say 100w. But I wish the topology i choose to be scalable as I have a 1kw Tesla coil I would be connecting to the amp as a baseline. I have a small coil like the one in the video also I may choose to use.

About the classD, it may be easier to just buy one, especially if you never built one before.

I don't think that should be a problem, as you've already built a Tesla coil. The video shows the Tesla coil's PWM being modulated by audio (music), making pressure variations that result in audible sound, that's it.
And, please try to have a Faraday cage around the coil, just in case ...
