Nakamichi Discrete 3 Head Cassette Recorder with Play Head Azimuth adjustDual Voltage international model Model Cassette Deck 1 120V/220V AC input Selector This decks great feature is the Play Head Azimuth Adjustment and no different than DR 1 Model in all respects except the CasingHowever this had not been as much appreciated as CR 5A which does not have this feature! Nakamichis strengths are its Dual Capstan Drive with Pressure Pad less transport and its Unique Parmaloy Heads. Also Nakamichi Electronics are pretty good internally with adjustments for Metering, Playback Level/ High Frequency Adjustment as well recording Bias/ Recording Sensitivity Level From my 15 years of regularly restoring these 25 Plus Year old Cassette Recorders, I notice that only with correct service using Nakamichi Tools you can bring the Nakamichi Magic back in its Sound performance. Low Noise and fantastic Dolby C ( Dolby Laboratories Developed Dolby C with Nakamichi ) in Playback and records beautifully So here I offer a nice No nonsense Cassette Deck 1 if you do not want to spend lot for Dragon or CR 7A but want a decent Nak After Calibration I enjoyed its musicality as much I enjoy a Dragon or CR 7A due entirely to Azimuth adjust for Pre recorded Tapes International Shipping may not be correct - please contact me for Correct Rate

Physical condition - excellent, almost no imperfections. Electrical condition - fast forward and rewind work but are sluggish. Play does work but sometimes stops unexpectedly. Probably needs new belts. Sold as is. I have recently acquired a very large collection of high-end audio from a world renowned collector and restoration specialist. I will be listing a part of it over the next week and then a larger part within a month. Please keep an eye on my listings for many great opportunities to find scarce pieces.
