As far as power going out and coming right back on, or going out and staying out 5 or 10 minutes or an hour, that happens here in western Pa. all the time, and often there is no apparent reason, such as a T’storm, for it. In the past I did not unplug my equipment, and in the days of yore I did not even trip my breaker. That wave of paranoia started quite recently. Probably since I started reading posts here.
I will say that I have never experienced any component or appliance damage. But I am not arguing with you guys about it. I never started wearing my seat belt until I lost my drivers license for a year when I was 31, and I never was injured or killed in a car wreck, but I was lucky and I know that they save lives. I guess I have been lucky with my appliances and components as well.
