BrandNew! (NOS) Sony SQD-2070 SQ Decoder. The unit is in theoriginal box and is still in the factory plastic with the original Owner’sInstruction Manual.

Thisbrandnew SQ decoderwas obtained many years ago from a Hi-Fi store that wasclosing.It has never been used. It comes in its original box, withall original interior packing materials and is still in the plastic wrap.Theoriginalowner’s manualis included as well. I don\'t think youcan find a nicer example of this highly regarded 3 IC design SQ decoder.

Will be double-boxpacked by UPS.
