Sony WM-DD30! Original box, MDR-62 headphones and accessories, near mint! RARE

Sony WM-DD30 boxed with MDR-62 headphones - YouTube. Near mint in original box, and with the original MDR-62 headphones (very rare). Very nice WM-DD30 in the. New center gear (no clicking), pinch roller and capstan ring. Mechanical in great condition everything is checked and lubricated , plays very beautiful (see video here above).

Unit is near mint and in very beautiful condition! Box does match with number in walkman.

New center gear and not a repaired/glued one. When the gear is glued this results in higher wow-flutter, so less good sound quality. Why do the original gears always crack?

Theyre usually made of POM material. This material is very reliable, long lasting and has very good friction properties. However, it has one negative property. It shrinks when it is heated, for example when player is left on sun or in car. By heating POM material to 60 C, it will shrink permanently about several percent.

It also shrinks with time. Problem is, when this gear is installed on some other part, for example on metal axle. Plastic material shrinks, while meta one doesnt. High tension in plastic part will cause that it cracks.

Some parts are made of other than POM material. This can be short lasting material, fragile, that breaks into several pieces after some time. Reason why this is important. It can curl (eat) some or all tapes.

It can cause speed variations. It can cause azimuth instabilities. Playback can be randomly stopped. Is responsible for the correct tape speed. Bad capstan is responsible for high wow flutter.
