Here is a video on how to clean Input select switch, Speaker select switch. Volume, Bass, treble & Balance control
May notice a channel cutting out or crackling noise
In this video I will be demostrating on a Pioneer sa 5300 Amplifier
But any make such as Marantz, Sansui, Akai, Sony, Yamaha, Nad, Rotel etc
would be pretty much the same.
