[VAL] Hum

Hello All!

I recently bought a 1976 Argosy 24 footer that Im quite pleased with because 
everything works.  Well, almost.  Im a music lover with sensitive ears.  The 
radio has a pronounced (60 cycle?) hum when running off the Univolt.  If the 
radio is the only thing on, the hum is almost imperceptible, but as the Univolt 
takes on more load (lights, electric cooler, etc) the hum grows louder with each 
additional device that is switched on.  Its not broken, just annoying.  Does 
anyone have a fix for this? Maybe some type of filtration?  The radio is not 
the original 8-track.

Thanks,
Duane Middlebrook
