Bachus, I believe that the problem may have been the result of corrupt power surges, which are quite common on many of the Mediterranean islands and also in the Caribbean islands, where I performed when I was a kid in the US Navy many years ago. When UPS systems became available at a reasonable price, I purchased one, though I rarely used it because of it's weight. Now, they are much lighter and electronically controlled to switch over so there is no lag time. When we encountered those kind of problems, the problem was never a high voltage surge, but instead, the voltage would frequently fall below minimum required for our gear, which resulted in either shut down, or lock up.
