NuTone SM428 stereo muisc controls

The Balance, Volume, Bass and Treble controls are missing their knobs on this SM428.  The original knobs tie the pairs of fader control arms together, so each channel is adjusted in pairs.

There is a "Stereo" and "Mono" switch, a "Stereo" indicator light which lights up when stereo FM reception is available.

A "Strength of Signal" tuning accuracy meter to provide clear radio station tuning.
