IC4 is your MB3756 voltage regulator. it is located on the right hand wall of the chassis, about mid way between front and back. this is with the component side of the PC board up and the knobs facing you. pin 1 is the closest to the back of the radio. do not confuse this with the audio chip which is on the same wall, but further back. good luck, matt |
