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

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
