Default damsel in distess..Sony WM D6C

Hi folks- I was wondering if anyone here had access to EURAS service.
I have a problematic Sony WM D6C Professional Walkman whose "symptoms"
are described perfectly on this web page:
http://www.euras.com/repair_tips_1/S...WMD6C_Sony.htm

see: Speed too fast. Cassettes move at approximately double speed.
(the remedy includes a circuit diagram)

I'm am a newbie DeVry student and would like to look over their tech
tip for this issue. Also am wondering how expensive the repair might
be.

Thanks for your help-
Karen

Sometimes a cassette witll run too fast if the pinch roller is not
pinching the tape against the capstan.
Look for a mechanical reason. The pinch roller could have just popped
out of place.

This is a known problem with some of Sony's servo-controlled portable
cassette decks. The D5 was prone to it too. As I recall, it was caused
by an open pickup coil in the motor assembly, causing the servo to run
wild.

Most likely, that's the problem.

There was a fairly involved procedure to replace the motor on these - the
original is no longer available, so the circuit must be modified.

The service bulletin number is AUD0395 .
