I don't want to scare anyone,but fire is always possible.A simple coupling cap shorting out can cause a tube to have thermal runaway.If a tube starts glowing orange,shut if down(the gear) as fast as possible.Solid state amps,tv's, and other electronics all have risks too.Homes burn down for various reasons,a lot are electrical,or electronic failures.
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?
