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?

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?
