I will sell the amp, but as you can see i previous posts, there "might" be a problem with it, It was once a very good amp in its day, and still it, but was cutting out once in a while. I suppose it had to do with the fact that I was trying to power a sub with it, but who knows. I will sell it for $10.00 + s/h o.b.o., so let me know if you want it. It is a Sony XM-2540 if you want to do some research on it. It is rated at 25 watts by 4 channels, and has only 0.04% thd.
