I recently found this in the loft. Not a very special cassette player being nearly all plastic, but it is one of only two cassette personal stereos I bought new for myself. At the time it was an impulse buy spurred by the surprise of seeing a unit with Dolby for £19.99. When I tried it out it wouldn't move the cassette so not surprisingly it needed a new belt. Fitting this was surprisingly easy. There is one screw holding the back on along with clips around the outside. With the back off the one belt was very easily accessible and thankfully hadn't left debris stuck to the pulleys. I borrowed a belt from a different set I had bought from Fix Your Audio and normal operation was restored. Cheaper than buying a new one https://www.ebay.co.uk/itm/AIWA-HS-GS302-Stereo-Cassette-Player-BRAND-NEW-/123741153775
