There are 8 tubes in the Doge. 4 12AT7s are the linestage and 4 12AX7s are the phono section. You can refer to pacificvalve.us for more detailed information.
Dpatterson, I have contacted pacific valve , they wrote back and said the 12ax7's are the linestage, nevermind letting me know what the seating position the input to the line are. So I am still looking for an answer or I guess I can put all four linestage tubes as low noise. Just cost a lot extra if you are using nos tubes.
