Not just switch off, completely unplug. I lost my Luxman amp, Bryston CD player, and Martin Logan speakers in a lightning incident. Fortunately homeowner's insurance covered most of it, and Bryston stood by their astonishing warranty, otherwise I would have been out a very significant amount of money
lightning storm
listening to my new Maria Callas vinyl last night and a huge thunderstorm/lightning storm starts up. About 2,3 seconds before each boom, I was getting a lot of static through my speakers. EMI from the lightning? I have no idea so asking the group. Thanks. Smart ass answers accepted also :-)
