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
