This unit has been in storage for the last 10years. I recently took it off the shelf unboxed it and sent it to the repair shop to bring it up to operating specs. It is now fully functional and ready for your home. There are a couple of scratches on the face plate other wise it is in great shape. Included is a factory original service manual.
