Complete service, not a repair. Every cassette deck that arrives here is 20+ years old and, in almost every case, has never been serviced before. Old grease hardens, oil in the capstan bearings dries out, plastic parts shrink and crack, rubber idlers and rollers de-vulcanize, electrolytic capacitors dry out and drift out of spec, and transistors lose contact with their heat sinks. Because of this, every deck goes through the same complete, standardized service procedure — not a spot-fix for a single symptom — including full mechanical service, azimuth and speed calibration, a detailed service report, photo documentation, a recorded test tape, and a warranty.
The 682ZX belongs to Nakamichi's 660ZX/670ZX/680/680ZX/681ZX/682ZX family, and is often described by collectors as having a noticeably warmer sound than both the later Sankyo-mechanism generation of decks and the earlier 480/481/482/580/581/582 series.
Full disassembly and inspection to record the condition of the mechanism, capstans, and belts before any work begins.
Old grease and hardened rubber parts are cleaned, replaced, or restored, and all moving parts are re-lubricated.
Electrolytic capacitors are replaced, and all switches, potentiometers, and trimmers are cleaned and tested.
Azimuth, speed, and frequency response are tested and calibrated, and a final test tape is recorded and reviewed before the deck is returned.
