I have already read a lot on this very interesting forum, it is time to take the next step. When I had my teenage walkmans (TPS-L2 and WM-DD) repaired, the virus caught me. Without being a compulsive collector I now have about ten (WM-2 red, WM-3, WM-7, WM-R2, WM-F2, WM-D6C), all operational and as many as possible with helmet and cover of origin. I even assembled myself a mini system at work Good day.
