The bias is permantly set on a Mesa . I think instead of biasing your amp to the tubes i thinks mesa's way of thinking is the other way round .

If you call http://eurotubes.com/ (phone # on home page) tell them you want to use JJ’s and which amp you have and they will select the tubes you need within the proper range for that amp.
