    That and there is a huge difference between a power opamp and an audio amp. Why do you think an LM386 is an appropriate substitute?

    Papa, I guessed it it probably wasn't. I hoping someone would say it would work OK. Or that someone more learned than I would explain why it is not an appropriate substitute. RJohnson just sunk my battleship. I am still interested in knowing where to look in a datasheet to find whether an op amp is stable at unity gain.

    Sorry about that. Often times the data sheet will say "Unity gain stable". I also think single supply are if not said otherwise but I'm not sure about this.
