So I just recently got a Sony WM-EX631 Cassette Walkman from eBay. Its been pretty good the first month, had to replace the cassette door on the transparent case but other than that fine. Now, it seems there is an issue with the autostop/autoreverse function. The cassette was intermittently reversing to the opposite side at random, like in the middle of a song. Once I changed the mode to not reverse, now it just stops as soon as I hit play even mid tape. I’m wondering if the mechanism for detecting auto reversing needs attention. From what I’ve gathered they use some sort of transducers on a reflective gear to accomplish this. Is that information correct? If anyone knows anything I’d appreciate it.


Thank you, I’ll attempt this the next chance I get. Hopefully I can source a new spring from fixyouraudio or something but in the meantime I’ll employ your method. I really appreciate the advice and just talking about Walkmans. When I get to it I’ll be sure to post an update here.
Np, good luck.
I miss my old Walkman from when I was young (actually think the one I used most was a Toshiba). Favorite was a Panasonic fm radio though, still love that thing, might have it in storage actually.
They were awesome for the time, best of luck with yours, ask if you have other questions!
