Hey there everyone. I just took on a restoration project of an old cabinet stereo/record player that belonged to my wifes uncle and I have got pretty much everything working except for the control knobs. Every time you turn one of them they make that loud crackling noise and you have to play with them for a while to get actual music to come out of the speakers. I know this is not uncommon with old stereo equipment but I was wondering if there was a way to fix that our do the knobs need to be replaced. If replacement is the answer is there an easy way to do it without messing up all the wires and what not. Any advice is appreciated as I am pretty much an engine and carpentry guy and know little about electronics. Than you.
