This is the Unofficial Nakamichi Cassette Deck resource since 1997

The Compact Cassette medium was first introduced at the Berlin Radio Show in August 1963.

In 1973, the Nakamichi brand was launched with the 1000 and 700 cassette decks. These two models, the world's first fully discrete three head cassette decks, were largely responsible for establishing the cassette deck as a viable source of high fidelity audio recording and reproduction. From that legendary beginning, the Nakamichi brand has introduced a series of revolutionary breakthroughs in both cassette technology and music reproduction quality that have continually redefined the standard of excellence in audio reproduction performance.

Gold plated RCA connectors

Found a direct gold-plated replacement for the ordinary RCA connectors.

This modification was tested on CR-1 and CR-2 but may also work on DR-2, DR-3, DR-8, Cassette Deck 1.5 and Cassette Deck 2 but with a different Pin Jack P.C.B. Ass'y. Other models in these series already have gold plated connectors.

Sankyo control motor cleaning procedure

On Nakamichi decks that have a Sankyo-made tape transport, it is common to see a problem develop where the deck's tape transport starts to act very strangely, and the deck may even stop responding to commands.

If it can be determined that the deck does have a good idler tyre, then the problem is quite often in the control motor mechanism. These photos will show a couple of techniques to address this problem.

Orange Cap replacement procedure

It is observed that large number of Nakamichi cassette decks start behaving strangely after years of use or storage (with very limited use) mainly due to certain make of capacitors losing their properties.

Engineers call this "Aging failure". Fortunately the failures are noticed only on Orange colored Polyester (or Mylar) Capacitors. This Document is meant to help DIY Nak users who want to replace these Caps and restore their Naks to fine working condition.
