Some of my old radios make a raspy.skritticy noise when I tune the dial
knob and or the on/off/volume control knob.Sometimes I squirt a little
dab of tuner cleaner stuff (or even WD-40) from a spray can and the
noise stops for a while.I don't know that much,but I do not believe it
is normal for any radios to make any noises that are abnormal when
tuning the dial knobs or the on/off/volume control knobs.I could be
mistaken though.I do definetly know WD-40 works great for my old
arthritis fingers.
