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!!

There are very detailed explanations of the sonic characteristics of various tubes (and they are grouped by tube equivalent) in Joe's Tube Lore at Audio Asylum.
