The amplifier can't adjust the volume?

The use of potentiometers is basically common, but most people report that they don't know how to repair the broken symptoms of power amplifier potentiometers, such as noise in use and adjustment failure. Then it is normal that you are not a technician and don't know how to fix it. There have been some common problems about installing potentiometers before. Let me explain to you how to repair the broken symptoms of power amplifier potentiometers.

Repair method of adjusting noise of power amplifier audio potentiometer

In general, if there is noise when adjusting the potentiometer of power amplifier, it may be that there is too much dust grinded out or entered, which leads to poor contact of internal components, that is, noise will be made when adjusting the potentiometer. Then for the repair method, first disassemble the potentiometer, clean the dust inside with alcohol, and then check whether the elastic force between the rotor and stator is large enough, which will also lead to poor contact. Then it is suggested that some lubricating oil can be added, and the contact is good under the condition of sufficient elasticity, which can reduce the friction in the use of potentiometer and is conducive to the maintenance of components.

Maintenance method of adjustment fault of power amplifier potentiometer

In daily use, the power amplifier potentiometer often fails to adjust the volume, for example, the sound is too small or too loud to turn off. So for the treatment of this kind of fault, it is generally possible that the internal rotating shaft of the potentiometer is damaged due to frequent use, as long as a rotating shaft is replaced. However, there is another possibility that the installation is not firm, which may lead to poor contact of some components inside the potentiometer and failure of potentiometer adjustment.

Treatment method of unbalanced volume channel fault of power amplifier potentiometer

On the power amplifier equipment, the volume of the left and right channels is unbalanced, which is generally caused by the excessive wear of the potentiometer. The maintenance method is inconvenient and can only be solved by replacing the potentiometer. If it is used for a long time, it will also lead to the aging and deterioration of some parts of the potentiometer, which will lead to great security risks in the use of the potentiometer.

It should be noted that in the use of potentiometers, do not change potentiometers with different specifications casually, because the resistance of potentiometers with different specifications is different, otherwise the potentiometer will be incompatible with the equipment and cause damage.
