Apologies if this question has been done to death, but I cant quite find and answer elsewhere...

Basically, dug out this old amp and a CD player to see if it still worked but the sound seems to go quiet in one speaker sometimes. If I give it a little knock on the right hand side (as you look at it) the sound goes back to normal.

Im wondering if someone could point me in the right direction for things to check first or possibly manual/Diagram of working components for me to reference against if I need to clean/replace internal components.

Any help appreciated!
