Default Two Transistor push-pull AB amplifier

It is probably going to be difficult to beat that : a push-pull with less than two transistors being a kind of an oxymoron.

Performances are not great, but it actually works: I have tested it, with slightly different components: a 2SC1983 for Q1, and a IRF520 for M1.

I have also tried with a TIP122 darlington instead of M1 (and no R5): it also works.

Have fun!
