@stereo5 Wow. I'd have to check receipts but when I bought the CV 4003 about 15 or so years ago they were about $100.00 for a matched pair. That was back in my early days with my tube line stage and just went with the advice I was given. Perhaps I might have obtained better results with the Mullard 12AU7.
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
