Tubes and their problems


I thought since I am currently having a few tube problems, and since i am not
that technically inclined, I would ask what are the typical warning signs and problems of our beloved tubes.
I will start off with the "popping" sound that I believe indicates either tube failure or impending failure ( perhaps someone can clarify why a tube does this?) What are the other various warning signs to look out for?

Daveyf, lets hope the bad tubes if any are in the preamp. I think you have some concerns but more importantly you are picking up a station I've never heard of.
PHd, I actually was referring to Al jazeera...lol..although that might not be the station, it could have been anything for all I know!
Anyhow, I am going to get a handle on which is the offending tube and replace it.
If your system is bringing in al-jazeera: look for tube with a beard and towel-wrapped head. Eliminate it, with extreme prejudice, before it blows up your house!
We all have problems. Tubes have their fair share. They must be good though or else nobody in their right mind would tolerate them. Same goes for records.

One of my problems is I wish I had fewer tubes and records. But I want things to sound really good and never know when I might want to play a record. That's another problem I have.

Problems, problems....

With my tubes I find they tend to get noisy over time. I have never had one just suddenly go up. Currently I have them in my ARC pre-amp only. No tube power amps. That's really asking for trouble. :^)

On the bright side (no pun) tubes tend to glow and look really cool, especially in the dark. Transistors can't do that. If they do you have real problems. Plus some vendors have even found ways to make the tubes look like they glow even more than they do. Now that's good marketing!
