Getting delivery on Thursday,and could use some help.
This is my first Decware amp,and I want to make sure exactly ,which tubes I can use?
I own many 12au7's....are these ok,remember,this is the mkII,not the mkIII?.
My other tubes,which I used on the Crack amp  are:
6080,6sn7,WE-421a,tung-sol 5998,and a GEC brown plate-are these OK?

Also,,I'll be using the Schiit Bifrost Dac
Will another dac ,be preffered with this amp.
Any help/advice will be greatly appreciated.
Thanks
Mike
