My first experience with FET's was at a station in SC. They had a TK27 film chain. One day it lost the luma channel. I had no clue, but the asst CE knew exactly what it was. The FET preamp blew out on the luma channel. It was mounted right up there on the target ring of the pickup tube. He said they just blow out every couple of years.
Static can take out an FET. There's a great deal of concern about a high altitude EMP blast taking out almost everything electronic!
