Tube Newbie question

I'm trying to learn more about tube pre-amps. I'm overwhelmed with the codes and test numbers for vintage tubes. Can anyone give me a simple explanation of what to look for in a tube? Does anyone know any good learning resources for this technology?

I've read in forums about people saying, for example, the 'Amperex USA made 6922', made their pre-amp sing. These are old tubes. Don't they wear out?

Thanks so much!!

One of the best introductions I have ever seen to the world of valve amplification can be found here - "A Taste of Tubes":

find a dealer or supplier with whom you can build a relationship with. this person can serve as a mentor until you develop your own experience and knowledge base...it's what many of us have done, myself included. other posters comments are also valid but find a tube source (I don't mean Ebay) and work from there.
welcome to the world of tubes....
