Recently refurbished, cleaned, adjusted speed, and replaced belts. Works perfectly and sounds great! It's size is barely any bigger than a cassette case. This is a 90s model, so it has been tuned better and has more features than the older 80s models, like AVLS and Anti-Rolling!
I work on Walkmans quite a bit and like to have them running at their best.
The FX-21 is from 1993. Own a piece of history!
Let me know if you have any questions.

PS: I have lots of Walkmans that I put up for sale, so check out my other listings. I'm always working on fixing some, so new ones get posted from time to time.
