Default op amp supply

I think you would want a op-amp with a higher supply then +-6v, when you have a 2Vrms signal amped about x2 you will start to loose a little of the dynamic headroom. I suggest +-12 volts as a minimum.

That's encouraging, I'll have to fire mine up again. Sorry I don't remember the details, it's been a few years. Now that I have a scope and resources like this site, I should have a much better chance of finding and fixing the problem. I'm thinking it would make a good headphone amp.
