The Norelcos were even favored by NBC in some roles, as the TK-42 and TK-43 were a lot less reliable, harder to repair and maintain. Which is why NBC kept the TK-41 in service for so long, and the TK-41 picture was hard to beat. The Norelco PC-60 and PC-70 cameras were very excellent, reliable and maintainable by enigneers, and made excellent pictures.
