Beautiful unit in black finish recently looked over and cleaned by Audio Research. Smoke free environment. Opportunity to own a Ref 3 with very few hours of operation. Original owner was an audio reviewer with Sound Stage, and I purchased from him on Audiogon 10 years ago with 805 hours on the original tubes, and added less than 1900 hours on the tubes it came with. Comes with new tubes from Upscale Audio with 65 hours. It has a small scuff on the top left corner that is not visible except at a close distance (see photo).
