I'm offering this Mclntosh Vintage  Preamplifier c31v  that's basically in pretty solid  condition. There are no crackling, pops, or other noises associated with this unit and all knobs and controls are firmly intact. As you may know, it produces truly great acoustics when paired with some really nice equipment. As shown in the pictures, the cabinet has seen better days, but it still looks good for it's age. Most importantly, No performance issues exist with this Preamplifier!!!!   a little light shines through part of the faceplate like some type of peeling is occurring as shown in the pics, I didn't think it was necessary to open the unit and view it closer because no performance issues exist.(please view photos carefully)  otherwise this unit doesn't require servicing to perform as intended. It will definitely be packed and shipped accordingly.  Thanks for viewing. Question?  please ask.
