"Fried" is a colloquialism used to describe damaged electronics. Dont take it too literally. It doesnt take many Watts at high voltage in the wrong place to wreck electronics. Fuses are not intended to protect electronics from failure, their main purpose is to pevent fire in equipment. Even surge arrestors may not prevent damage. Protecting against the kind of overvoltage experienced would require circuits specifically designed for that purpose. Either they did not exist or had been bypassed.
