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.

My injectors are class D but I only run them in class A. I generally bias with IAC adjustments but sometimes fuel pressure.
