    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/Sony/WMD6C/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
     
  2. 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.

    Sometimes a cassette witll run too fast if the pinch roller is not
    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.

  4. 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 .
