	Something is different, there.
	Might try adding a bit of sealant?
	(might it be mistuned?  Voltage peak in the middle?)

	Dunno.  Mr Mod?
	I thought there was a note on the bottom of the mailings?
	Look Here:

	I would.  I'd also like to hear other views.
	_near_ is the operative part.

	And get the 'puter, monitor, anything else shut down
	and OUT, as several have suggested.

	(probably overcautious: better safe than toasted...)

	Again, coil size helps define the risk.
	How big (power) is the system?
