Can someone tell me how to hook one up? Does it just wire up to the course clarifier wires and
isolate the fine clarifier wires? I've asked all
over the place and no-one seems to have an answer!
Surely someone knows here on the Copper forum?
Thank you.Slim |

The only way I know is this:
Cut the BROWN wire loose where it connects to clarifier and tape it back. unsolder RED, YELLOW AND ORANGE WIRE from clarifier. Remove the clarifier control and install the 20K-10 turn pot in its place. Looking at 10 turn pot from the rear, solder ORANGE wire on the rear terminal, the RED wire to the middle and the YELLOW wire to the front terminal. trace YELLOW wire to board and cut it loose and solder to circuit board ground. Trace red wire and cut it loose from board and solder an exrtra length to RED wire and solder it to PIN 3, THE UNUSED PIN OF IC-4.
Next locate R174(12K) resistor and remove it from board. Replace it with wire jumper and solder it in place. Locate R44(8.2K) resistor and D52, being careful cut one end of each effectively removing from circuit. It does not matter which end of R174 AND D52 you cut. Now it should anywhere from 15 to 30khz and smooth as silk.
HOPE THIS HELPS!!!

just remove the old pot, remove the wires, solder them to the new pot(an ohmmeter would HELP to find the correct tabs to solder to), install the new pot. if it tracks the wrong direction, just reverse the 2 non-common leads. |
