Groove tubes in a Booogie?

[makeuacaster]

My understanding is that Boogie biases all their amps so that you never have to rebias when you replace the power tubes . . . right?
But let's say I want to, or I have to because I'm in bumf*#^ Nebraska and a tube breaks and all I can get are Groove Tubes . . . which numbered value Groove Tube should I use? (6L6's of coarse)

Go to the Groove Tubes website. 6L6's with a ratings from (if I remember right) 4 to 6 are Mesa approved.
