There is a problem with the volume of the amplifier. Is the potentiometer broken? How to repair it_ Some friends reported that the amplifier used has problems with adjustment noise, adjustment failure and imbalance of volume channels. Is there a problem with the potentiometer that caused these problems? How to repair it? Today I will tell you how to deal with these faults. The use of potentiometers is generally widespread. However, most of the personnel reported that they did not know how to repair the broken symptoms of the power amplifier potentiometer, such as the noise in the use of the potentiometer and the failure in the adjustment. If you are not a technician, it is normal for you not to know how to repair it. I have also told you about the common problem of installing the potentiometer before, so I will explain to you that the power amplifier potentiometer is broken

Causes of potentiometer noise_ The potentiometer is actually a variable resistor. Because its function in the circuit is to obtain the output voltage that has a certain relationship with the input voltage (applied voltage), it is called a potentiometer. Dynamic noise of potentiometer When the potentiometer is under the action of applied voltage and its moving contact point slides on the resistance body, the electrical noise generated is called the dynamic noise of the potentiometer. Dynamic noise is one of the main parameters of sliding noise. The value of dynamic noise is related to the shaft speed, the contact resistance between the contact point and the resistor body, the uneven change of the resistance of the resistor body, the number of dynamic contact points and the applied voltage. Sliding noise is
