The amplifier has been disassembled cleaned refurbished and calibrated. 

It was then tested and has a smooth clean well rounder sound output across the full frequency range maintaining its clarity at full power. 

The power level at 1/8 volume fills a 2000 square foot room completely. The amp actually amazed me compared to others in its class. 

It has one tiny blemish on top side corner. I have used a close matching mix of model paints to conceal it and you have to look very closely to distinguish it.

It will give you endless hours of reliable wonderful sound and if any issues I will be glad to work with you to resolve them.

I downloaded a manual and will include it with amp.
