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.

Seems to be a few sublimal messages going on here. PBNaudio. Stanwal's message was rather cute however Atmasphere's was even better. Hey,I hope you guys know how rebias those output transistors when required.

(I just had a feeling someone would pop in and trash my overly simplified explanation!!) Makes me all smug and happy, makes them all smug and happy, so we are all happy! and the Op is happy too. (but is he smug???) What a wonderful world we live in!!
