The sound and the stereo image are excellent, the bass is tight, the vocals are very defined, the high frequencies are crystal clear, both in playback and recording modes. The cassette mechanism run smoothly. Externally the deck is in almost excellent condition, considering the age. This is a 120V/240V model, S/N 05482. With the deck are included the old parts. All the questions are very welcome. I moved recently in US from Greece, where I was working in Greek Nakamichi service during 90's and I have all the professional equipment (original test tapes, oscilloscope, wow & flutter meter, distortion meter, frequency response meter). If you need to service your deck I'll be happy to help you. See also my other items and my feedback. Please ask for shipping cost. Usually is 35$ to 85$ with insurance by Fedex ground.
