Fox,
I work for a TV station in the third market of the US. I would be fired for taking that attitude. Failure of a component that was thought to be suspect that results in a loss of air time is unforgivable in my line of work. We recently replaced a $35K output tube on the transmitter for fear it would cause a loss of air time based on a several factors it exhibited in operation. One of which is a nearly two day replacement time window. While the tube tested fine, there was enough doubt in it's continued operation that the decision to replace was made.
Mark,
Good luck!
