John The new grey wire was contributed by G4SPZ . They were originaly black .TYhe potentiometer was removed and replace just the same .I took pictures before i removed it from receiver .And to bring up a point the hum was there from day one .And before i replaced the potentiometer with the new one .Phil told me the right one to chose from CPC .And after it was fitted it cured the problem of a bad crackling as you moved it . But not the hum . If the wires on the pot were wrong the volume would not work as it should .But i will check it out on the other receiver just in case . I do have pictures some were .I will see if i can find them .
