To Gary, who owns the ICF-2010 with the potentially 'hot' chassis --
Several electronics products connect each leg (hot and neutral) of the
AC line to the chassis/green-wire ground with "Y" capacitors to reduce
conducted EMI. If a product like this isn't grounded (i.e. the green-wire
ground is broken at any point), the capacitors divide the AC line voltage
in half and the chassis floats at half line voltage (65v).
I consider a 'buzz' from any equipment pretty serious, and I recommend
tracking down and fixing the cause of the problem.
Good luck,
