RT-909 Output, MIC output, Line input knobs won’t turn independently.

Hello, I just picked up a Pioneer RT-909, I just went through a basic functions test and everything seems to be working properly. My question to you is; is there a trick to making the Output, Mic Output, and Line Input knobs (left/right) turn independently? The schematic indicates that the inner and outer knobs should both turn, but I can’t get any of them to do so. They all turn right and left together, but not independently.

Thanks,

Gary
 
Try pulling the outer knob (R Channel) slightly out of the splined shaft, then attempt to turn that knob cw and ccw to work it free. It's possible there is galling between the inner and outer knobs.

Thanks! I have already downloaded the the manual. I applied a few drops of Deoxit to the inside shaft, hoping it acts like penetrating oil. I’ll try it again in an hour or two.
 
Perhaps, drop into the "Introductions..." sub-forum to introduce yourself and your passions. I'm interested in what else you are running in your system.
