Undertow, I did view your system, very nice! When you upgraded the caps, did you do it yourself because it looks like a very fine job? Anyway I checked my PP1 and there are no 12AU7s shipped with it (as Matrix mentioned), just what is printed on the circuit board next to each tube is exactly whats in there. I am also going to look into your tube recommendations. I personally think each of us here sharing the same thoughts have definately walked away with a wonderful tube preamp for a ridiculas price. Vlad has definately out-done himself!
