Keys and volume in electronic circuits are among the parts that get damaged over time, apart from the discussion of depreciation, factors such as dust also cause their damage We see it many times in the car amplifier, since some models of keys are not available in the market for purchase, we use them according to the speakers connected to the jumper amplifier. and for the RC sockets in the models where the ground base or the same ground is towards the input, we open them from paper Chinese broadcasts or digital devices and receivers.
