Which 6SN7's for Rogue 99 Pre


I was just wondering which 6SN7 tube you guys with Rogue 99 Magnum pre's are using. I have been using Sylvania VT 231's and the BAD BOYS with great results, are there any others?

I agree with Maxmad. RCA Gray glass are great and don't cost an arm and a leg. Ken-Rads are very good also.
The RCA VT-231(grey glass/bottom getter) will lend a warmer(tubey) sound to the mids, the Ken-Rad VT-231(black glass/bottom getter) a cleaner presentation. Otherwise: they're about equal in detail, imaging and sound stage.
The combination of tubes that i have found most to my liking in the 99 is rca blackplates in the first position of each channel followed by a sylvania bad boy chrome dome in each of the second positions of each channel, this may not be to everyones liking but it sure works for me in my system!
My friend borrowed a pair of brimar 6sn7 Gty's from me and said they sounded great in his Rogue.
All the tubes mentioned are very nice. Which tube sounds best will depend on synergy with the rest of your components, not just your preamp.

I have all of the finer 6sn7s. Changing just one component most of the time,warrants me to change out the 6sn7s in my preamp for better synergy.

So,what works best in someone's 99 probably won't in someone others IMHO.
I'm using RCA VT-231 with two Sylvania Bad Boys in a headphone amp.. Terrific combination, but I have to say these tubes really benefit from Herbies Tube Dampers. In fact, two dampers down at the bottom of each tube is an entirely different ball game.
