Very rare upgraded “ii” variation of the Nakamichi 600. These don’t pop up very often. This one’s been stripped down, cleaned, lubricated, tested, belts replaced, idler tires replaced. 2 of the original buttons (as they notoriously do) went missing. I had custom 3d printed replacements made for them and color matched the best I could. other than that everything is still original and as it currently is plays, and records and sounds good, however this likely needs to be calibrated with a cassette calibration tape. the heads were aligned to the best of my ability without one. this is standard for all used cassette decks. it well be well packed and shipped fast.
