Here is my HS-JX303. My missus got it for me for Christmas. I had one of these when I was in my teens. It is absolutely pristine. Looks like it was rarely used. The only thing missing is it's HP-V14 headphones, but luckily I have a spare pair.
It appears to function perfectly, but I might have Retrodos give it a service for me. A great Christmas present!
Well now that is a wife to keep. Great thoughtful meaningful gift to be sure. Nice unit and working too. Nothing better than having a Walkman that you had as a younger guy when they were the rage.
