This is a great sounding classic phono stage. I think it started off as a PH3. At some point it was updated to the PH3-SE. This has the same tubes that came with the phono stage when I purchased it. Theyre good tubes. There are better tubes out there, but it is quasi-religious, so I keep tube selection to myself. There are a few small scuffs/scratches, but no dents or signs of abuse. It runs quiet (no audible transformer hub, and no hum in the signal). Satisfaction is guaranteed, but return shipping is on the buyer. I will protect the original box with an even larger box. A box, in a box, in a box. Boxity box box BOX! Let me know which service in your area is the least crappy. I will usually choose UPS, but your UPS driver might suck, so let me know. I do not ship outside of the contiguous 48 states (no foreign bidders or would-be bidders). I have been buying, selling, repairing, designing and importing audio for a while. If you have a problem, its probably easily fixed.
