Not sure about where you live but here the 110 volt line is 120 volts normally. It used to be 110/220 years ago and then it was 115/230 but is now standardized at 120/240.My guess is he may have some older gear that was designed when 110 volts was really 110 volts or less. Some old tube gear that was meant for 110 volts does not like the higher voltage we generally have today as the filaments run hotter and some capacitors are running at or above their voltage ratings. My home has about 125 volts on the "110 volt" lines which is quite common.The pole pig is located at the end of my driveway which serves my house and one house each side of me. The volts are a bit higher than the normal 120 volts because of the long secondary run to the neighbors however the 125 volts I am getting is rock stable and just at the high end of the acceptable limits of proper voltage. I have had a few pieces of tube gear that actually had the plate supply voltage exceed the filter cap ratings because of this.
