NOS tubes for Sonic Frontiers Line 1

I just recently bought a Line 1 here on the Gon, Sounds great, but, I would like to do a little experimenting with some NOS tubes. I under stand the back two tubes make the biggest difference.
I would appreciate any suggestions? It now has the Sovtek 6922 stock tubes.

Thanks, Jim

I also have a Power 1. Soon after purchasing it I started tube rolling. Right now I'm using EH kt-88, 2 BB-6922, 2 EH 6922 and 2 BB 7308 in the drivers.

From what I read, the 2 rear drivers have the most impact on the sound, so I started with the 6922's. With my equip (AR LS2MKII w/ 6922 PQ, Jolida jd-100 w/RCA 5751 blackplates and Dahlquist QX-10) the system sounded decent.

Interestingly, when I moved the EH 6922 into the rear drivers the sound stretched vertically, and became much more 3-D. Go figure.

I used to be a professional artist, and since getting into tubes I've discoverded each tube-type I use colors the sound, differently.

So much fun, but oh so costly, sometimes. When my wife returns my charge card I want to try out a matched EIkt-90 quads.

Anyway, enjoy your Power 1. I think mine is boss!

Jea48: Based on your posts are you saying that the 2 and 3 slots yield the greatest results? The reason I ask is I have two sets of two matched pairs (Electron Tube, Russian) and Amperex Greens, as well as a complete set of 6 Amperex JAN 7308 Greens. All of the tubes came from Upscale Audio where the Line 1 was originally purchased. I started playing with rolling the tubes over the weekend, but wasn't quite sure what to do with just a set of 4. Sounds like I can still play.

Jim:
Please post your observations when you get the Herbie's Dampers. I am interested to hear how you like them and what changes you observe.

Snipes,
The 2 tubes in the far back row Will yield the biggest change in sound, LV1 and V1.
Next is the middle row, LV2 and V2.
Front row, LV3 and V3 least effect.
I learned this from Bill and Sam.

Question for you. When not listening to your SF preamp do you put it in standby or shut it off completely? Looks to me that standby shortens the tube life. Is that right?

Jeffcott, yes I will let you know.
