[R-390] Crayola front panels

[Bob Camp]

Hi

I suspect that the radio works at least a little bit better with the 
front panel grounding the shafts on the controls. I doubt it's a big 
deal, but I would not deliberately isolate them.

The second issue would be safety. With the shafts grounded an 
accidental short to the shaft does not give you a "hot" knob. Again 
that's a pretty rare thing, but 200 volts on the knob would be a bit of 
a surprise.

	Take Care!
