Subject: Preventing Recurring Damage To Amp IC And                              Date: November 10, 1995
         Power Supply IC.


Symptom:
  (**)         The HA13151A audio amp IC or the BA3910B/BA3918 series of power supply IC
               may sometimes be damaged by incorrect wiring connections or by counter-
               electromotive force generated by the vehicle's power antenna relay. The symptoms
               vary dependant upon which section of the IC fails.



Solution:      If either of the above IC types is found to be damaged replace it, and prevent
               recurring damage by adding 2 diodes to the IC as shown below. In those models
               which use both types of ICs, add the diodes to both ICs even if only one is damaged.
