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.
Yeah, i enjoy posting simplistic nadderings so the 'real' smart folks can jump in and save the day!! (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!!

It wasn't "oversimplified." It was wrong. There is a difference. It is possible to put things in layman's terms without being wrong.

If I post something that is incorrect I hope someone jumps in and corrects it. People come her to share and learn. That is impossible if we allow errors to go unchallenged.

If Elizabeth enjoys posting misinformation as she says and that makes her feel smug then this forum is worse off for it.
