What if the repeater is mute?

This can also happen when household appliances are often not used. Do you have any wine at home? If there is alcohol at home, you can wipe the head of the repeater with a cloth dipped in alcohol, which will definitely improve the sound quality of the playback. Because the repeater is not used for a long time, it is likely that most components of the repeater are wet and some capacitors in the repeater are aging, which leads to the decrease of the sensitivity of the repeater and the unclear sound quality.

Wipe the playback head with alcohol first, and then put the repeater in the sun. This sounds like a joke. Although this method is a bit stupid, our goal is to improve the playback quality, so as long as it can improve the playback quality, there is nothing we can do. Wipe the playback switch with alcohol, and the playback quality is not clear, because the speaker is wet, and then the dust enters the drum basin of the speaker. Then the touch switch in the middle of the view is rusted, which leads to poor contact effect and unclear sound quality. ...

Secondly, I wonder if you have an electric soldering iron at home? If you have an electric soldering iron, you can turn on the repeater and re-melt the tin spots on the back of some components that look wet, so that all the components that look wet can be re-melted, which can improve the soft fault of the repeater.

You can send me a message if you have any questions.
