and void your warranty?.....

One cheap tweak: on the ground leg of your bias pots, install a small electrolytic cap (or film if you can find the space) to ground. Usually the ground leg has a resistor to true ground. A 5 to 10uF cap is sufficient at say 50 volts to be really safe will buffer the bias to the tube tremendously, and give your amp a significantly greater control of the bass. Remember the positive leg goes to ground for the bias supply.
