m1225 no audio output

I have a m1225 radio that has no audio output. I checked the speaker connections and the pins at the rear of the radio and have also connected an extrernal speaker, no audio. I believe that the audio output IC is bad but cannot find my prints for this model radio. I am wondering if anyone can point me to the correct IC and location of the IC on the board that is the audio amp.
Thanks

The audio IC is pretty easy to spot, big 9 pinned one mounted to heatsink on the left side (looking from front top of radio).

Moto part # is 51-80147R01
