NOS Tubes for Rogue Tempest II


Looking for some suggestions replacing the stock tubes. I want a little more transparency or pop yet retaining overall smoothness and good bass. I want to start with the 12AX7's and the 6SN7's first. I was told the Sylvania 6SN7 GTB would be a good one but there are several versions so I am a little confused. Also the same with the 12AX7 what is a good value without breaking the bank.

I have a rogue stereo 90 and run ge 6sn7 gta's. Those and ge 12ax7's. I tried mullard and telefunken 12ax7's and didn't care for them (either too forward or too lean compared to the ge's).
Like Detredwings stated above,tube choice is a very personal subject.That being said,in my Tempest II Magnum,I have found that I prefer NOS Amperex 7025 in place of the 12AX7's, NOS Sylvania JAN 6SN7 WGTA's and Gold Lion KT-88 power tubes.Try some different tubes and find some you really like then stock up on them.NOS tubes are getting scarcer and pricier as we speak!!Good luck.
For starters I have some NOS Sylvania 6SN7 GTB (tall) green labels coming soon. These were very reasonably priced and suppossed to be very musical. I might try some TungSol tall which are recommended also.
Hi Sam - I don't have a Tempest, but a pair of M180s, and have been experimenting with the 12AX7 tubes recently. I called Rogue before starting and asked for some tube recommendations, and they were very helpful.

I tried NOS Mullard CV4004 and my impression is that it is warm and laid back. I also tried NOS Sylvania 5751 and prefer it to the Mullard - it is clearer and seems to have more life to it (in my system), and it throws a nice soundstage.

I also tried a new production Tung-Sol for kicks and giggles and actually found it to be better than I'd expected (this is the first new production tube I've tried). It is a different sound than the Mullard and Sylvania - much brighter with crisper bass, overall just more "concise". Not bad for the money though, IMHO.

I've also got some NOS Telefunkens en route - I'm curious to see how they work out.

Good luck!
Jerico I found the NOS GE triple mica black plate that I had stashed to be much more precise and less fuzzy than the stock Sovtek 12ax7LPS so I can relate. Let me know how the Telefunkens workout please!!!
