@Mr Trev - 12au7 hey....I got a few from previous tube amps, I think I got a 12au7 Gold lion Genelex as well...would love to try it in the Vali 2. Does the adapter keep the tube from drawing too much power? Might order an adapter this week. @bcowen - If you got good eyes, try reading the markings/lettering on the Tele's, apparently that will give you an idea on which factory they were made in. I believe the 'real' Tele's came from Germany and there are other's manufactured in by Philips?
