i live in Colorado USA. we get a lot of lightning here, even in the winter. i've had my house hit three times, the first time it hit a large ground plane antenna on my roof. the only damage from that one was a PL259 connector blown apart. another time it damaged some phone jack wiring and fried an answering machine. the 3rd time, it hit the transformer on the pole. in the house, only a DVD player was damaged, but it took 4 hours for them to come out and replace the transformer. i saw it happen, lightning hit the transformer, and a bunch of smoke came out of where one of the insulators for the primary had been. i've repaired TVs and audio equipment damaged by lightning that had wrecked a large portion of their sound and video systems. i've seen receivers and amplifiers where all that was left of the bridge rectifier in the power supply was 4 wires with blackened ends. i always get the "but i had it plugged into a surge protector????" my answer is simple, lightning has already traveled several miles through the sky, and a 1/8" thick silicon disc isn't going to have much effect on where it goes in your house wiring and audio/video gear. if lightning damages an AV receiver, chances are good that there are several things fried, and they are usually the things that are the most expensive to replace. 90 percent or more of stuff that gets damaged by lightning are not economically repairable.
