Tube failure -- what would happen in worst case?

How do you determine when a tube is to be replaced?
Can a tube ever glow bright red and blow up?
If it does, would it damage the amp itself as well as other components including the speakers?

Bad cord or problem with wireless xmitter? Rectifier problems? I don't know a lot about this stuff but,I'd check the common failure parts before taking it to the tech shop. Might be an easy fix you can do yourself. Also, it will save you some cash and embarrassment (believe me, I know about embarrassment)!!!!
