Personally, I've found that as good as it sounds when biased as recommended, and having the pre-amp / power amp tube combination that I have, it actually sounds even better when I run it with the bias even lower... say around 85-86mV. I think it's cool how all these seemingly small things have such a noticable effect on my tone.

PS. Let us know how those Tungsols work out for you. I have some currents production Tungsols and haven't used them yet... Not sure where to stick them at this point!

Plop those Tung Sols in V1 or V2 or both just to see. Then you will prolly go right back to your NOS combo hehe. I like the Tungy's and the Mullard RI's but I can tell the NOS we have are bettering them tone wise to my ears. Playing blues and rock dynamics are really important to me. Not so much when I play metal. Just a wall of pound serves there and the NP's can do. The Chinese 9th generations are good for metal.

That being said I would run those 2 NP I mentioned in V1 or V2 with no worries. I have already. Sound wise I like em' for what I like to play.
