I am creating this thread to make a list with all the significant threads I created about walkman repairs and specific problems. Given the TechTalk section is very crowded and threads go down very easily, I will also have the link to this thread in my signature, for easier acces to all the important content I have created and will create in the future from a single link. It is very likely I missed some of the links, but will be updated later. More to come ! NOTE: In this context, by WM-DD series, I'm reffering to walkmans that have a center gear type mechanism, like WM-DD, WM-DDII, WM-DDIII, etc. WM-DD9 is very different than the ones with center gear type mechanisms, so not covered by generic WM-DD threads.
