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.

Cary v12. Apparently you can use a meter, or just turn the screws until the lights come on. Seems easy enough.
HEHEHE. 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.
