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.

I had a Cary V12R before the CAD 120's. You need to use a meter, not just depend on the red led's. They run hot, but are a great amp. The led's show that the tubes are good. Happy listening.
