Would it hurt my amp to run 2 Yellow Jackets and 2 6L6s? Would I need to rebias?

You were asking me about this earlier and I found your answer.

For an interesting blend of sounds, you can even exchange two of the output tubes in a four tube amp for Yellow Jacket Converters and leave the other two as 6L6s or EL34s. This blends the sound of both and lets you run a combination of Class-A and Class-AB.

For your AT-series B52, its a four tube system, and the pairs are (A) (B) (B) (A), so you'd pull both A's or both B's and replace them with yellowjackets, and you would not need to rebias as the yellowjackets ignore the grid bias yet still show up as "there."

I actually might do this when I can afford the yellowjackets and a quad of 6L6GC's (Never running without backups again...)
