Open clarifier
1)Remove the radio's covers. Top & Bottom and face plate.
2)Behind the face plate find the clarifier control pot.
3)With a DC volt meter locate the pin, on the clarifier knob, with 5 VDC on it and cut the trace going to it.
4)Cut D-21 on the main PCB.
5)Jump R-181
6)Solder a 4.7 K resistor from SJ-32 to the closet leg of the clarifier.
