I ended up playing around with a couple mosfets, a LM393 comparator, NE555 timer, and other stuff and I made myself a decent amplifier, but the inputs I used for the comparator were a square wave running at about 1Mhz and the audio source itself via a capacitor. I also connected a resistor voltage divider to the same input and this divider made things work well. (example: I made the input at ultra low volume and can hear the same thing very loud at the output)
Now I'm curious. In my design, I used a square wave as an input to the comparator. On the web, the majority of the designs use a sawtooth or triangular wave input. I'm curious. Why is the triangular wave input preferred? What is the disadvantage with a square wave input?
