This is an early model with the built-in tuner, but with the cool black nobs. Original owner and the amp is in excellent condition. There is nothing wrong with the amp, I'm just interested selling this and buying other things. Comes with rack-mounting hardware. Sold as-is, no return. For details and specs see: http://euphonicaudio.com/index.cfm?page=iamp800 Buyer pays shipping and insurance. Paypal payment is acceptable. Feel free to PM me with questions.
