[R-390] MC/KC knob dancing

[Todd Bigelow - PS]

Many thanks to all who offered advice and suggestions. The 'gears need 
cleaning' part rang a bell, but for the life of me, I couldn't remember 
the detent/spring part. Although this unit appears to have seen little 
use, the metal could still be fatigued I'd guess. At any rate, it tells 
me right where to look when I tear back into it. I ned to get after the 
band/crystal deck switch as well, so maybe it'll make a good weekend 
project. Forecast is for rain again, so why not? Too wet to plow, too 
windy to stack BBs...
