    Nope. You can bias the amp hotter or warmer, but it will work equally fine with Mullards or JJs. The real issue is the plate and grid resistors, but adjusting these doesn't affect the bias. The stock 100 ohm and 1.5K values should be bumped up to 470 ohm and 2.2K for longer tube life, particularly with modern tubes (not as rugged as Mullards, which barely clung to life in an AC30 anyway). This should be done for Mullards, too, as the amp will run cooler with longer tube life with no tonal tradeoff. It was, frankly, a mistake made by Jennings back in the day.

    Seems to me that if you put a booster in front of an AC30 you can get almost any kind of tone you can dream of...aside from metal.

    Saw Rory Gallagher 3 times. He always used a vintage Vox AC30 sometimes with two Marshall late 70's JMP combo amps.... pure rock tonal bliss !!!

    Well I hate to be so harpy on it, but when you hear the difference, you will wonder why you didnt do it earlier. Yours is one of the last extra harsh/brittle sounding ones left floating around out there.
