Electrical question

Once again there seems to be a lot of people who can't read or, and this is more likely, want to act like they know what's best and post info that isn't necessary nor asked for. Every, dang, time.

At the least need to get the microwave off that line..with the Pass XA-25 amp and First watt sit-4 going with the Pass pre-amp Dac and tv it maintains 119 to 118 volts…when my wife turns on the microwave and I am yelling at her don’t do it if falls to 113 to 112..

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.

@boomerbillone I usually have the Panamax where I can’t see the Volt meter which is on the same line where some stuff is plugged in when she turned on the microwave on it freaked me out. It’s been doing this for quite a while didn’t notice it before. Probably just get the microwave on a different line. 

Just put in a new circuit with heavy gauge wire, like 20 amp.  And use a hospital grade outlet.  Thank me later.
