I have many Tascam Portastudios with rubberized knobs- the 488 and 688 for example. They seem to have degraded over the years and got sticky and gummy, just like a belt or a pinch roller. Is there anything I can use to harden these back up a bit? Would alcohol work? I’ve tried running a few down with alcohol with no real success, I’ve considered soaking one but I don’t want to screw up any of them any further. Has anyone found a good way to fix this issue?
