Sony WM-D6C Professional Walkman.
Still one of the finest pieces of audio equipment I ever had. Dad brought it back from Japan in about 1988 and I absconded with it right away. It was a brick and sounded like no other tape deck on the earth… Smelled of quality electronics that you could only buy in high-end type shops.
Sadly, I think it’s long gone. Perhaps time to find another.
