Can someone please suggest any online store selling quality belts Or if someone is having a replacement belt for Sony wm-fx521 ?
I suggest buying your belt from here: https://fixyouraudio.com/product/belt-sony-wm-fx521/ Marian (owner of FixYourAudio) is a member of this forum and his belts are of very good quality. You can also find pinch rollers if you need them.
@Valentin - I am new to this forum.. I tried finding Marian but no luck. Could you please tell me his user name OR include him in this chat. Actually I also need a pinch roller for my sony wm-w800. So just was to confirm with him.
Marian's username on the forum is mihokm, but he's not very active on the forum. I suggest contacting him via the website's contact form here: https://fixyouraudio.com/contact/ In regard to the WM-W800, not sure if that roller is available. If it's the same as those used in WM-10/20/30 units then it's not available, at least I'm not aware of it. Those pinch rollers have a special hub that triggers the auto-stop mechanism, so it must either be replaced with a roller that has an identical hub or just the rubber itself.
