Cosmetic Description: 7/10 Very good cosmetic condition with some minor visible cosmetic wear including some light scratching on the top surface and sides and minor tarnish on the tube bed chrome and tube covers. The TV out thumbscrews are missing and the faceplate edges are tarnished and although they can be pulled off fairly easily stay on just fine. This item shows some wear consistent with its age but is still presentable and sounds wonderful.
