Model:      XR-U770/U880                                                    No.    354
Subject: Audio Distortion, Noise, No Audio From One                         Date: February 21, 1995
            Channel, Tape Mechanism Malfunctions Or Does
            Not Operate At All.


Symptom:
  (53)          The above symptoms may appear if any of the electrolytic capacitors in the unit leak.
                The actual symptom observed depends upon which capacitor leaks.



Solution:       A parts kit containing all of the electrolytic capacitors found in these models is
                available from the National Parts Center. Although the unit may exhibit only one
                symptom, all of the applicable capacitors should be changed to prevent additional
                symptoms from appearing in the future.

                The applicable capacitors are made by ELNA and are red. Furthermore, only those
                red capacitors which are printed with a number of "235" or lower, or in the case of a 4
                digit number "9235" or lower, need to be changed.
