Here is a Vintage Sony 10 Disc CHANGER Magazine EXCD 1RF 1 Bit D/A Converter System Works AS/IS. This was working when last used but no longer have cables or DC power cord, so selling AS/IS. Mounting holes have been damaged when previously mounted but i'm sure would still work fine with a washer , please see pics. These are rare and hard to find.  Buyer to pay fixed shipping cost of $13.99. Thanks for looking.
