Serial Number UANN004614CC. Used in good condition.  Knob cover on Rec Level is missing but still functional.  Limited testing: it powers on/off, disk tray opens/closes. Don't have other equipment for testing recordings. Does not read discs. There are scratches on the left side from trying to remove adhesives from a lock mount.  Those are just on the rack mount, not the actual component. Power cord is included.
