MR-80 was supposedly the MR-78 with digital readout. The unit is in very good condition, the glass faceplate shows not scratches or cracks. The walnut is included. Unit was gone through 5-6 years ago and worked great when retired a few months back. Selling the unit because lack of decent FM stations in my area does not warrant a high quality tuner like this one. Manual included is a copy of the original tuner. Rating is based on the age of the tuner, not its condition, which is excellent.
