Here's the second hand walkman I found online. It was supposed to work but didn't really do when it arrived. The seller was a really cool person, genuinely surprised by the video I did to show him the malfunction. He insisted on refunding me and told me to keep the walkman. Now I have no other option than fixing it! I suspect that the issue is an old loose belt, fixyouraudio.com might have a replacement. To be continued.
