[QUOTE="warmachine67, post: 154584, member: 3696"] You can mix types in a module without any problems. I have had luck even using a 12at7 in either one or both positions of Fender type modules. I've mixed 12at7's with au7's and ax7's in any arrangement and it changes the headroom to varying degrees. But, 5751 is great too and sort of between a 12ax7 and a 12au7. You usually have to go somewhere online to find them since GC probably won't stock then. Whatever you choose, I recommend using a JJ brand in the right hand tube (looking at the face plate / knobs) position. [/QUOTE]
