Would like to prevent this so Googled using AC Power Surge Protection
and found "The Best Surge Protector by Brent Butterworth.

I do not have a technical background so would be interested in
others comments concerning all this.

Would like to use your advice to build a cost effective audio
protection system.

**The best way to protect an audio system from "power surges" is to
disconnect the TV antenna during lightning storms, since that is, far
and away, the most common source of "power surges". Mains bourne "power
surges" are incredibly rare events and almost nothing available off the
shelf can deal with the energies involved.
