OK! The verdict is in! I hooked up one of my voltage regulators in between the wall and the APC. According to the APC it is putting out a steady 118-119V to the APC. SQ you ask? Can't tell the difference. My peace of mind? Much better.
I have left the APC alarm setting at 134V as a "just in case".
Thanks for your input.
