I was searching the web for a push-pull audio amp circuit that could produce 10 watts. I came across on on circuittrue.com with an op amp feeding TIP122 and TIP127 transistors. It looked like what I wanted, but as I looked at it, I couldn't see how it could possibly work. The op amp output does not feed the base of the transistors. The transistor bases are connected to the + and _ power inputs of the op amp.
Can someone please explain how this could actually work?
