Stickman as I mentioned they should work without issue but if you go to the web and look at the tube data you will notice significant differences in the voltage and current characteristics of these two tubes.
Kind of like driving a Porsche with a Chevy engine in it. It may work but it's not how it was designed to run it's best. I wouldn't spend a lot of money on nice tubes just to try it. But that's me.
Maybe just get some nice 12au7's like Rodman mention all he said are nice tubes. I have a friend that uses the EAT tubes and really likes them but I am not willing to fork up the money to try them.
