Do You Unplug Equipment During Thunderstorms?

Yes if you can.  A direct hit can fry almost everything plugged in but not always in my experience.  One time it did.  Another time it didn’t.  Lightning is an unpredictable phenomenon.  Better safe than sorry.  

Yes, I do.  We have a lot of thunderstorms here in the Tidewater area of Virginia.  I plug all my equipment into a Silver Circle unit, so I only have to unplug that one unit, which makes it a lot easier. 

Used to when I lived in Southern Illinois; in Southern California, what's a thunderstorm?

Yes I live in Montana have a whole home surge protection for the service comes into our meter and yet there was a lightning strike hitting the power line 2 years ago that blew all the fuses on the power poles for miles. The whole surge protection breaker did not trip and fried all of our televisions bedroom sound bar and my recently purchased PS audio m700 monoblocks. I have added a Furman just in case but yes I absolutely unplug now.

My current system is on a dedicated 20 amp circuit supplying power through a hardwired isolation transformer, and then a non-sacrificial  line conditioner/surge protector/voltage regulator. We don't get that many thunder storms in my area, but the the service has an annoying habit of randomly blinking off and on with accompanying brown outs and surges, necessitating the protection I use.
