Hi, I want to try to fix up my crappy Samick - the volume knob needs either fixing or replacing. The stupid volume knob will work only when set at 98%...not 97%, not 99%, not any other setting except one sweet spot. It's either 97% or NOTHING... I've tried cleaning it with pressurized contact cleaner and compressed air but that only lasts for a few hours, then it gets crapped up again. I want to remove the volume knob and replace it but I don't know how to remove it. The volume knob on the front isn't screwed to the rest of the volume control and I'm afraid to pull it off with pliers. From the inside, the volume control isn't screwed into place either. My friend says the volume knobs are "friction-fit" and you can just pull the things out. But then again, my friend has never done this kind of operation before. SO.... Does anyone have any suggestions as to what to do? I would like to try this myself first rather than taking it to a music store. The volume control is shot anyways so I can't really do much more damage to it.
