Agreed.... my preamp is very sensitive to noisy tubes. I have a JJ 6922 in there now. Just put a brand new Gold Lion in, noise. The Gold Lion tube is dead quiet in amp but rush in pre. . So i put the JJ back in. Sounds very good, not quite as good as the GL...still sounds really good, just different . Im going to order a super low noise tube .....
Can’t use any other tube??!!?
I just got a used Rogue Cronus Magnum 2, and I want to roll a few tubes I have into the center 21au7 spot to see if I can beat the stock JJ.
Every tube I try is noisy - crackling and hissing. Even tubes that I take from another amp where they are crystal clear.
But when I put the JJ back in - it’s quiet again.
I have tried new production Mallard and two different NOS Mullards.
Any ideas why only the stock tube is working?
