   comes out from the speakers.
   Take the following actions against the above problem.



   1) Attach CUSH -S, PWB.
   2) Connect the anode of the DIODE, 1SS133 to RES, 10 -1/8W by soldering.
   3) Connect the cathode of the DIODE, 1SS133 to the Q008 connector by soldering.
   4) Connect RES, 10 -1/8W to the plus side of C035 by soldering.
   5) Apply glue to the cathode of diode.
   6) Apply glue to the terminal of resistance.


    5) Apply glue to the cathode                                     3) Connect the cathode of the
       of diode.                                                       DIODE, 1SS133 to the Q008
