This was working and has been completely refurbished about eight months ago. It has all new silver wiring and so many parts in here I can’t name them off. Originally modified by Rick Colleen. Probably better than any of the new ones out there as far as sound quality is concerned, depending on your current power conditions, of course. I’m going to have to let this one go. I’ve sunk enough money into it. Already an embarrassing amount I will not disclose. I believe all it needs is caps, but I’m not sure because I heard a popping sound. I believe from the black cap in the picture. You see caps completely replaced along with countless other parts. It was working brilliantly for eight months straight . There will be absolutely no refunds on this whatsoever since I’m selling it as is /parts machine. However, most of the parts in here are about 6 to 8 months old. This is as far as I’m going to take it. Next audio file up gets this item. Shipping in the original box double boxed from PS audio original packaging. Ideal for the tech out there that loves clean power and that can repair this. May need board replace or retrace.
