Sony Walkman - Model Mapping and Overview Table

I was inspired by many other members here on S2Go.

Sometimes it is not easy to find out some details of Walkmans, as the service manual is nowhere to be found:
for example the WM-EX911 thread by @RTB in which I suggested a tape mechanism similarity with the EX511 (based on that service manual).
Other times, a model has many different variants that are not documented yet:
like the WM-2 thread by @JUAN ANDRES MONTIEL DIEZ and findings from @Valentin in it.
Other examples are the clutch problem @Valentin posted about recently.

To not lose oversight of all these details, I decided to start with the overview included below.
It took me a while to log some of these findings.

Now I am now looking for active contributors to a) update existing information, and b) insert new Walkmans!
I could use help too with how to integrate details from the common problems thread and/or repair tutorials thread, even if just links to the right threads per (group of) Walkman(s).
The source file includes - besides the overview - 1 sheet per Walkman.
It is available on Microsoft 365 for online editing.
Please send me a private message if you would like to contribute!

Thank you.

 

Thanks for the likes so far! Let me know what I need to do to make contributing more interesting.
Would we need a static page/thread here on S2Go to link appropriate information to specific models or ranges? Anything else?

 

Thanks for the feedback
The larger version can be opened in the pop-up, show original: http://stereo2go.com/forums/attachments/2021-12-sony-model-mapping-draft-png.33108/
Still not original resolution, and a bit outdated since a few changes have been made to the source file..
