Pioneer sa-710 right channel problem

[TimBabyFace]

Hello I have a question for anyone who can help my Pioneer sa-710 intergrated amplifier is in great cosmetic condition. The only problem I'm noticing is the right channel get's really scratchy and sometimes go's out . If I play with the function knob it clears up but it takes several tries to get good full sound. How do I tell if it just needs a cleaning or if it's something else? And then if it is just in need of a good cleaning could someone please explain step by step how to do so correctly? Thank you for your time I really appreciate it.

This is a pretty good indication..

You have a dirty switch..

I thought so I was just worried about a broken joint. Is there a good way to clean the pot without removing it?

The function switch is a slide switch.Not a "pot" potentiometer. Its is best removed and disassembled to clean the tarnished/dirty contacts.
