Product Description and Further Details:

This Sony Walkman is in excellent working condition and shows remarkable quality for its age. The back panel is in excellent shape with only minor noticeable scratches visible on the black anodising, and all four original feet are still in place. The front panel has some scratches visible on the black anodising in the right-hand corner, and the screen-printed Walkman logo is in great condition apart from some minor chips. The plastic chassis band is also in excellent condition. The felt surround for the switch line is present, and all screws are intact and in good condition. The battery holder is in good shape, with the slide-on cover included and no signs of corrosion. The cassette door has some very tiny chips visible on the black anodising, and the window is in great condition, as this has been replaced with a new window. The window has been securely refitted into the door. Overall, the Walkman looks fantastic and functions perfectly, delivering outstanding sound quality with very minimal wow and flutter (explained in detail below).

Wow and Flutter:

Wow and flutter refer to the wavering in a reproduced tone or group of tones caused by irregularities in tape drive speed during recording, duplication, or playback. This can result from changes in the angular velocity of the capstan or issues like the dragging of the cassette shell. The terms "wow" and "flutter" are often mentioned together, with flutter being a higher-rate version of wow.

All tape players have some degree of wow and flutter, and most manufacturers indicate their measured tolerance for specific players when new. Be cautious of claims of zero wow and flutter when purchasing these units. Various factors can increase wow and flutter, primarily due to age and usage, such as dirty or dry moving parts, including the capstan, pinch rollers, heads, and motor wheel—especially after a belt change. Worn belts, size, quality, and pinch roller issues are also significant causes of wow and flutter. All these potential causes are meticulously checked during my refurbishment process. Additionally, deformations in the cassette compartment can lead to issues, but this depends on the quality and condition of the cassette used. I always recommend performing a complete rewind and fast forward of an older tape before playing, which can help minimise playback issues.
