Hello charles007100! Normal voltages in the USA run 110 - 120 volts AC. Do you take showers when the washing machine is running? Have you felt the surge of cooler water on your delicate hide? Did you survive? Don't sweat the small stuff! A surge is much worse that a drip of 10%. If your gear has reguated power supplies, it won't even notice a small fluctuation. We had a fire that damaged the power lines. The bulb in the bathroom night light actully scorched the wall paper behind it. I measured surges of 165 volts. All my gear survived. Relax! Enjoy the music.
