One thought on “CD WALKMAN DISCMAN (1990)

  1. I have a 21-year-old Sony Discman D-99 bought in 1991 that is still working with no problems – only some artefact noise when you turn the volume wheel due to some dust inside but once the volume is set the sound is as crisp and clean as from day 1. The battery, needless to say, is gone and I only use the AC power supply. Is this vintage device worth any money, do you happen to know anyone who might be interested?

    The AC power supply is 220-240V/50-60Hz for German sockets
