Current production preamp tubes maybe try a Mullard RI in V1 they are a lower gain 12AX7
Would this help? (excerpted form eurotubes)
ECC803 S - 12AX7
Factory description: Classic long plate European design with special grid plated by gold to reduce microphone interaction and noise.
My observations: This is the latest 12AX7 offering from JJ and once again it's a beautiful sounding tube. It's the longest plate 12AX7 type tube ever made. It has the same deep, tight low end that the ECC83S has but the mids in the ECC803S are even thicker and more harmonically complex than the ECC83S. The ECC803S is also a little hotter in the high end than the ECC83S. These are however not as high in gain as the JJ ECC83S. The ECC803S's are about 10% lower in gain.

I haven't used the ECC803S's but I have the 83S's. So from practical experience I cannot say. I just wanted to offer some other tubes besides JJ's which sometimes I wonder if alot of players get steered that way here without trying others as well. Nothing against Eurotubes which happen to only sell JJ tubes and will present them as a better tube. I actually tried them and prefer other tubes so I don't agree with the write ups there.
I do appreciate the how to bias vids there though which is how I learned to do mine. That was invaluable to me so I am a fan in that regard. Just don't like the JJ preamp tubes I've tried in my amp when it was in its stock form.
