When I stumbled upon a broken Sony WM EX112 Walkman, I couldn’t resist bringing it back to life. In a world where everything is disposable, repairing vintage tech feels like a small act of rebellion. Here’s how I fixed my Walkman and why you might want to try it too.

Cassettes are back

Cassettes are back on the scene. Analog is in. I want to make mixtapes again, after Austin Kleon’s example.

My brother and I used to spend hours crafting mixtapes of our favorite radio pop shows. We would painstakingly hit record and pause to avoid the DJ’s chatter, creating our own uninterrupted music experience.

I found a Sony Walkman WM EX112 for a bargain. I couldn’t wait to use it again.

Repairing the walkman

The spindle didn’t run. That meant the drive belt was probably stretched or decayed. So I looked for a replacement belt on the Internet. To my surprise, you can find a belt for almost any old cassette player. I found mine on fixyouraudio.com. I believe they are based in the Czech Republic; anyway, the belt will arrive within 2 days.

Not sure if it was luck as well to very quickly find a real service manual for this Sony Walkman. This was a rare gem in a world where everything is designed to be replaced, not repaired. By the way, if you ever retrieved such an old manual, save it immediately in your archive, an archive folder, or a tool like Evernote. You never know if this website will still exist the next time you need the manual.

Opening the walkman for repair is a small challenge. There are no screws, unfortunately, but you have to open some clips. That could be more convenient. This video explains how to do it. In the service manual are more details. First, press the clips under the lid with a screwdriver so that the top of the plastic case comes loose. Then, carefully follow the numbering and open the other clips in circles. Carefully, although it requires a fair amount of force.

Once you have it open, replacing the string is a straightforward process. You’ll notice the string wrapped around the spindle. Carefully remove the old string. Then, take the new string and wrap it around the spindle in the same way as the old one. If the string has popped off, cleaning the wheels from the rubber cake is a good idea. In my case, they were still clean, and the problem was just that the string had become very limp.
