    in reply to: Potentiometer humming #11584

    Hello Grant,
    Thank you for your information.
    If the noise only arise when you touch the potentiometer.
    You may have touched its metal part. When the body induced current is connected with the metal part, the noise will arise.
    So please try to just touch the plastic part of potentiometer to see whether noise still arise.
    Any more question, please feel free to contact us.
    Best regards.
