Electrical question

@charles007100  congrats on your Lucera.

Pass gear Sit-4…

Maybe reach out to First Watt.  Personally, I wouldn’t risk it until I know it’s safe

Sounds like your microwave and audio system are sharing the same circuit.   Less than ideal, but the temporary voltage drop should not cook your audio gear.   If this is prolonged, and your audio gear has a weak power supply, then it could cause premature failures of sensitive integrated circuits (chips).

Sonically, I would expect you would hear it, and that would annoy me to no end.   You could try AC regenerators, but the real solution is that both the microwave and your audio system should be on independent dedicated electrical circuits.

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..
