Hi,

I have recently discovered in the back of my cabinet an old American DJ Q-2221 2 channel mixer. Surprisingly, everything works except for the left hand line fader. It does produce sound, but it is very unstable. Sometimes it will crackle when used (a bad connection somewhere I know), and on rare occasion the whole right speaker output won't work unless you push the fader to the right.

I know this is a problem with the fader, but where should I go from here. Should I open the mixer up and see if there's a loose connection or water damage? Could I be able to buy a brand new fader somewhere? Any other advice?

Thanks in advance.
