around the vol/color/tint controls later. Then IIRC went to separate
dials w/ spotlights then the big chrome knobs & side controls.
Been a LONG time so I may have missed something.

Only probs I remember were a few of the drums, ft gears, I think
shafts ( clutch?) . UHF probs usually were bad U shaped grounds. Later found a few drops of WD40 cured them without the fuss & risk.
Also some U tuners had a flywheel driven by a thin metal rod.
Clean it good & would work agn for years.
