Conrad Johnson Premier 140 6922 tube swapping


Hi

I recently aquired the above amp and the stock 6922 is a bit noisy, I sure I have read that this tube in the C-J should not be changed?
Is this tube a candidate for tube rolling and suggestions of a new tube?.
I have read good things about the EAT 6922
Thanks
David

Hi all, Will someone please explain/provide some details on the problems with the stock version of this amp? Is it really factual that one needs to spend $2300 to ameliorate he design flaws? I have one in my sights but may decide against.
