Conrad Johnson ARTsa amplifier

For sale is this Conrad Johnson Artsa tube amplifier. I purchased this amp about 3 years ago here on Audiogon. I don't know the history before that. Amp works perfectly and sounds great !!  There's scratches on top of the transformer cover. Scratch kind a long but can't see too good unless the light hits it at the perfect angle. Hard to describe, took pictures. Had to walk around the amp to find that one spot I can capture the scratch in the picture. I have the original shipping box, manual, factory screwdriver for bias adjustment for tubes, the tubes that came with it (don't know total hours), and an unknown power cord. This thing is heavy ! So I'll need a day or 2 to ship this out.. Can deliver. I'll ship with FedEx, included in the asking price. Please send any questions. Must have some positive feedback if shipping. Thanks for looking.
