Thanks for making this, I do remember getting one back in the early 80's, however that is no longer around, shame I threw it out many years ago now.

I'm going to get out my Dad's Walkman on the weekend though and see if it still runs. I kept his Walkman WM-F2015 https://www.radiomuseum.org/r/sony_walkman_fmam_stereo_cassette_player_wm_f2015.html as I knew it was special hopefully it still runs, if not I will fix it!
