Eh, it’ll work but I hesitate to recommend using them. We regularly get calls and emails from folks mentioning their BHK pre is popping, hissing, etc. They mention that they have tried multiple tubes so they know it’s not a tube issue. The guys in the lab then test it and sure enough, it fails AP. Check the tubes and 9/10 there will be non 12AU7 inside.
That being said, absolutely roll the tubes and have fun with it. Just know that the Pre’s tolerance is only so wide and one could run into noise issues.
