Tube rolling on PrimaLuna P2

Newbee, you didn't use NOS 12AX7 tubes though, right? You used EI 12AX7s. Did you try any other tubes? I have the Two and I'm thinking of trying some Mullards.

oops, I think I remembered a previous post from you incorrectly or just assumed the EI's were new production. sorry! Yes, I plan to try power tubes but first I want to try some 12AX7's and the the AUs. I agree, 6550's would be the ticket. Although, it is probably going to be a year before I get around to the power tubes.

I was thinking Mullards because I tend to think that my speakers (Axioms) are, if not neutral, perhaps lean towards bright. If were overly critical and in a bad mood, I might say that. I actually don't think the amp with the stock tubes is anywhere close to being too warm. I never did find out what tubes came with the unit.

Yes sir, I sure did and I like them a lot. Highly recommended. I also put in some Amperex 7316s and this gave a more energetic feel to the music. You can't go wrong, really. I liked this amp with the stock tubes for that matter. With the Mullards and Amperex's, everything is more precise. Tonality is better with the Mullards.
