For some reason, I wound up redoing my electric plugs to try and get most of them in my best Power Conditioner.
This resulted in myself plugging my Nucleus into an Unfiltered outlet on my Furman IT15.
My Nucleus always gets a little “warm,” but never closer to the “hot” side.
I just happened to put my hand on top of my Nucleus after changing the plug outlet because it just felt a little warmer in the area. It was definitely on the hotter side.
I changed it back to a regular outlet and it almost immediately went back to its normal temperature!
Not sure if it would have burned out, but just this temp difference I indicates to — NOT USE UNFILTERED INLETS FOR OUR NUCLEUS!
