Ah...yeah. I went through that yesterday.
The knobs have a square nut inside and the set screw.
Remove the screw and put some PBBlaster or WD40 inside, and start working the knob. Rotate while pulling. DO NOT pry, you will crack the wider thinner knob behind.
Do no take off the keys, you do not need to.
PS. From the front our radios are very much the same: 5-band equalizer, and the same bands.
The rightmost key is, I think, FM and engages the second drive for the FM while releasing the main drive for the rest of the bands.
If the drive makes squeaking noises, this is the knobs front-most support it goes through. I lubed everything and it kept squeaking until I lubed the fron-most one.
PPS> I just looked at your schematic. They are exactly the same radios, meaning the chassis-wise. Mine has more speakers. And mine has the changer. But we share the chassis'.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
