Hi Pablo!
Just for your information, there are currently Valvo's in there. The more "tubey" types of tubes that I have researched are those from Valvo, Mullard, and the NOS Sovtek 6H23N EB mentioned above. Try out www.audioasylum.com under FAQ and look for Joe's Tube Lore,I believe, for an in depth discussion about 6922-based tubes. Also Kevin Deal at Upscale Audio is a hell of a good resource.
In my research, I have heard most people say that changing the tubes in the V1 and LV1 position affects the sound the most. A minority of people say the V2 and LV2. No one that I have come across has mentioned V3/LV3.
Enjoy your preamp when you get it!
David
