Has anyone run the radio with a 5 volt adaptor? Does it have a problem with
the 1/2 volt overage?

Thanks in advance,

Because a silicon junction voltage drop is fairly stable 0.6-0.7
VDC,in general. A small light bulb (here we go,another incandescent!)
in series is fun to experiment with as well,since the current
consumption will be visible.
