Tubes... what do they do?...


I really mean it...

What is it that tubes do, say for instance in a Preamp or Amp..

What exactly does the tube do, what is/are it(s) function(s).. and how does it acomplish it..

Thanks...

It is the equivalent of the transistor in your solid-state device. It takes a music signal and amplifies it. It is what makes the amplifier amplify. For the how-do-the-work part, yes, do check out the articles posted above.
It above referanced link is an older one but still just about the best introduction. It is a bit funny, the writer spends so much time talking about how out-dated tubes are and then, at the very end, he retreats...just a bit.
