1 of the 2 nuts holding the IEC socket was off. I wondered why the owner did
not hand me the "lump of metal" that he discovered wedged in an active area,
he probably dropped it trying to retrieve it, from a visible but awkward
place. The screw was in place , with a tight fit , not threaded, through the
IEC. Owner out of contact for a few days, so stymied , in case I'm inferring
too much, ie 1 nut only.
