Hello everyone.
I am building an audio amplifier using transistors, based on a circuit taken from "Art of Electronics". In the book, the circuit is presented without load resistance, and I understand quite well how the circuit works in general. In my case, I need to have an 8 Ohm resistor at the output, and I can notice that the output voltage is cut. I changed the circuit a little bit and experimentally changed some values, and in that case I can get some better sine wave. I want to know what is the impact of 8 Ohms on the whole circuit, and what are calculations for getting resistor values, because I don't feel good if I know how to get there experimentally, but lacking theory.
