    I recently put some JJ 6v6s and an Eminence Canis major in my Omega modded Hot Rod Deluxe.

    When I really drive the amp, it has a bit of a fuzzy sound to it. It also breaks up extremely early.

    Just wondering, is this because I didn't rebias the amp yet?

    Could be bias and could be the speaker just needs some time to break in.

    Thanks.
    I had 6L6s in there, and Jim biased the amp for those. That would mean I'd have to lower the bias since a 6v6s saturates quicker, right?

    Hard to say. You just need to bias the 6V6's into the correct bias range for the plate voltage. Bob

    That's what the 6v6's do, break up earlier. I tried this once and found it was breaking up too soon for my taste and I lost all of the headroom I was accustomed to. You need to rebias , Eurotubes explains the process and gives you a target value for the 6v6's.
