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

If you can find matched Tungsrams they won't disappoint. What are the stock tubes?
That probably is their stock tube of choice. Very commonly spec'd tube. They don't totally suck - in fact, when mixed with NOS tubes in my SF Line 1 they do a fine job of adding bass slam.
