Regarding #4, JJ tubes do not have a good reputation among audio tube people. However, Rogue may have built their preamp to sound good with them and if it is hard on tubes, JJs may be stout enough to handle the punishment, while other tubes may not. Best bet is to talk to Rogue about it. See if they recommend any other tubes.
Questions from a Tube Preamp newbie
I have my Rogue RP-5 back from warranty repair and I am loving how it sounds. While at Rogue, they installed 4new JJ 12au7-s tubes. Sounds great. I have some questions.
1. with about 2 hours daily playing, how long do typical preamp tubes last (I have heard Rogue's, like CJ, can be hard on tubes)
2. Do new tubes need broken in? if so, what is normal time frame?
3. Does tube rolling really make a difference on a preamp vs power amp?
4. What is the general concensus on JJ tubes for a preamp? Again, I am really happy with the sound, so I probably won't change. However, I will eventually probably get the itch.
Thanks

rodge827 ++++++++++ Andy has the best tube test equipment on the planet OP get started with this, no need to wait till your JJ need replaced you will find it adds an interesting aspect to learning to listen for small differences and sometimes massive change all for relatively small $ and have others have said get you some spares in the process |
NOS Tubes - Go to Brent Jessee! http://www.audiotubes.com However, I have been amazed with Gold Lion signal tubes, I have no reason to go back to NOS. |
Thumbs up to both Brent Jesse and Andy at Vintage Tubes . These places have quality product and a wealth of knowledge . Also of interest is Brent Jesse’s site that explains the sounds of various NOS Tubes . I find the descriptions to be spot on . Also sorry if I ruffled any feathers on my Mullard description . I also appreciate the number of knowledgeable Goners that have chimed in on the New Production Gold Lion Signal Tubes . I have their KT-77’s and KT-88’s and found them to be excellent. Somebody mentioned Cryo ? Was the change noticeable? I also appreciate Wolf and Lowrider . Good info guys , thanks . |
@buellrider97 I mentioned using Cryo'd Gold Lion 12AU7s from Cryoset. I don't know if the cryogenic treatment has improved the sound of the stock tubes but I can attest to how long they remain quiet in circuit. Ron Sheldon at Cryoset also tests the tubes carefully to supply you with matched pairs if needed. |
