Potentiometer (Master Volume) 100K Linear
The internal carbon resistive track has likely undergone oxidation or mechanical wear, creating microscopic voids or high-resistance patches. When the wiper arm moves across these patches, it causes rapid fluctuations in the audio signal's voltage. Replacing the potentiometer restores the smooth, continuous electromechanical contact required for silent operation.
