This amplifier came from the surplus inventory of ATS and was sealed inside its cellophane package when I got it.  I opened it because there was a rattle coming from inside the unit.  There is a small yellow plastic piece that broke off the outside cover which I've shown in a couple of the photos.  The unit is still held securely together so I'm not sure how important this piece really is.  I'm listing the unit as refurbished because I'm not sure of the its history yet the label on the package indicates it is surplus inventory so it's safe to assume ATS made sure it was in working condition before packaging it up.  Please check out all of the photos.
