The amplifier volume control is delayed. What can happen to him?

Question

Electronics

There is a music center Technics SE-CA1080. When increasing (decreasing) the volume from both the remote control and the knob on the tuner, the amp does not respond immediately. Sometimes it can generally be silent or yell to its fullest when turned on. Need help. Where to look for a malfunction?

Answer 1

I dare to assume that there are digital potentiometers, for example, encoders (twists) are hung on them, so, in this place you need to start looking.

Well, so, look as much as you want - you
'll find a bald trait.

Answer 2

analog potentiometer (the part on which the twist is dressed), poor contact of the slider
