I have a little-used Sony Walkman Professional WM D6C

I inadvertently reversed the polarity on the power supply mini-plug (not the
Sony original - the PSU that I used has a variety of mini-plugs which can be
configured negative or positive on the central pin).

The mechanism is now running far too fast - playback, rewind and
fast-forward.

It is too fast even when using batteries.

Can anyone help please

The motor servo control circuit has something blown in it. This would not be
easy for you to service yourself, unless you are experienced in this type of
troubleshooting, and can work with SMD technology. Your best bet is to give
it out to a Sony authorized service rep, or a place that is capable to
service your unit. Take consideration that the repair will not be low cost.
