What the heck is bias anyway?


I'm getting a new tube amp that will need to be biased. The process of doing it seems fairly straight forward, but I am curious: what are you actually doing when you bias an amp? In english, for us technical Ludites.

Thanks for the reply Atmasphere. I really would like to try tube amps, but I'm not mechanically inclined at all. I'm a plug and play kind of guy, which is why I have solid state amps. I'd consider tube amps as long as they don't require much fiddling around with. I think I read somewhere on Audiogon about self-biasing amps. If that technology exists, why don't all tube mfgs use it. Is self-biasing expensive to implement? Is it as accurate as a manually biased amp?
