I remember changing a switch on an AVC. It had caused the whole bus to lock up. It was 20 minutes to airtime and they really needed that bus. I changed the switch in 15 minutes with 5 minutes to spare.
Have you ever heard of Duca-Richardson? I think they morphed into the Ampex switcher division.
Maybe the worst switcher I ever saw was a Cohu. It was an integrated switcher in which the MC switcher and the production switcher used the SAME electronics. Yikes! So if your electronics went down, you were SCREWED! I never saw that happen. It did use redundant power supplies though.
