NOS Tubes for Rogue Tempest II

In my Rogue Cronus Magnum for the 12 ax 7s I have used the sylvanias 5751, but prefer the little warmer sound of Tungsols 5751s

From what a mainly gather most people seem to like the 5751's better than the 12ax7. The two times I have tried 5751's in place of 12ax7's they sound more musical and focused.

The 5751's work well in my unit too. I like to roll tubes as it's give a very different presentation. I'm currently using Sylvania 3 mica black plates with some Mullard's and it's a very midrange centered presentation. Sometimes I like the GE triple mica black plates together with Valvo tubes and when I want things to sparkle I through in my Siemens combo. All have a very different sound. Each has some advantages and disadvantages. But ultimately it's up to you and what you prefer.

Hey Sam - my Telefunkens 12AX7 arrived today, and I'm liking them a lot.

I've been doing a lot of rolling the past several days (both 12AU7 and 12AX7/5751), but came full circle back to the RCA Clear Top 12AU7As now paired with the Telefunkens - this is a very nice combo. Airy, spacious and more high end sparkle than the Mullards (when paired with the same 12AU7s). I think I still prefer the GE 5 star 5751s to the Telefunkens, and the Telefunkens over the Mullards, but I'm going to stick with this combo for a while.

Hey thats good to hear about the 5751's over the Telefunkens. You might think differently ;) What do you like better about the 5751's? Are they more precise, less fuzzy, and focused or do the Telefunkens have more top end energy, etc....

I got my tall bottle NOS Sylvania 6SN7 GTB in last week and have listened for about 3 hrs or so. They are much better than the stock tube thats for sure. They are very open, airy, strike a nice balance from top to bottom. I don't find any one area where they are out of balance from what I can tell so far. I wonder what I may try next. I saw some rebadged Sylvania's for Baldwin on here for cheap. I think they are black plates made in the early 60's but I have a feeling the ones I have are better.

What are you using for power tubes?
