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!

        Little update, the seller is just sending me a new unit. I will still attempt the heat treating though. The unit I currently have is really cool and it would be a shame to leave it in this state.

          So I remembered how the autoreverse worked on my toshiba, there was a roller on a rocker arm with a spring, when that roller displaced from tension the rocket arm triggered the action.

          I’m pretty much positive it’s the spring, but you might be able to test this by finding the rocker arm and adding tension with a paper clip to see if the problem stops.

            Thank you for all of your advice. The mechanism seems to be more or less the same with this unit. When I get home tonight I’ll take a look at the springs on the rollers. The design of this unit means I gotta take it completely apart to get to them but it will be worth it.
