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).\u003c\/p\u003e\n\u003cp\u003eWork Completed on This Unit:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAll internal dirt and dust have been removed and cleaned.\u003c\/li\u003e\n\u003cli\u003eNew motor pulley rubber has been fitted.\u003c\/li\u003e\n\u003cli\u003eNew belts have been installed.\u003c\/li\u003e\n\u003cli\u003eNew idlers have been fitted where necessary.\u003c\/li\u003e\n\u003cli\u003eNew pinch rollers have been fitted or cleaned as needed.\u003c\/li\u003e\n\u003cli\u003eThe capstan has been cleaned and checked.\u003c\/li\u003e\n\u003cli\u003eOperational parts have been re-oiled or greased as required.\u003c\/li\u003e\n\u003cli\u003eAny dry solder joints have been re-soldered.\u003c\/li\u003e\n\u003cli\u003eCapacitors have been replaced where necessary.\u003c\/li\u003e\n\u003cli\u003eContact cleaner has been applied to all switches, contacts, and potentiometers, with DeOxit.\u003c\/li\u003e\n\u003cli\u003eThe playback head has been realigned (azimuth) where needed.\u003c\/li\u003e\n\u003cli\u003eThe playback head and tape path have been demagnetised.\u003c\/li\u003e\n\u003cli\u003ePlayback speed has been set using a lab reference tape and oscilloscope.\u003c\/li\u003e\n\u003cli\u003eA full external sanitisation and clean has been performed.\u003c\/li\u003e\n\u003cli\u003eAny other necessary bespoke servicing or repairs have been completed.\u003c\/li\u003e\n\u003cli\u003ePolarity protection has been fitted to protect the servo.\u003c\/li\u003e\n\u003cli\u003eAll functions have been checked where possible.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease note: Everything shown in the pictures is included with the unit, and I've described the item to the best of my ability.\u003c\/p\u003e\n\u003cp\u003ePlease Note:\u003c\/p\u003e\n\u003cp\u003eThe unit is fully operational and functions as intended.

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.\u003c\/p\u003e\n\u003cp\u003eAll 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"RetroTechnical","offers":[{"title":"Sony \/ Black","offer_id":62899749192010,"sku":null,"price":1550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/2081\/6458\/files\/084a5baf-dbed-4347-8089-3d67948dd572.jpg?v=1786137048","url":"https:\/\/retrotechnical.com\/products\/sony-walkman-cassette-player-wm-d6-fully-operational-serial-no-42370","provider":"RetroTechnical","version":"1.0","type":"link"}
