If the Voltage or Brown out in most cases, the Power Company is responsible for the Damaged equipment. I’ve seen cases like these back in the day when I worked on appliances.Several years ago , a brownout/spike shorted windings in the power transformer of my Marantz 4400 receiver. Next day I complained to the power company and they bought the transformer and delivered to me. All good again. One in a million cases.This is less believable ! They had a guy in charge of solving/compensating for those (their fault) events !
I still dream working on appliances, makes me mad I can’t collect a paycheck for it lol
