I discovered Supratek by chance when I came across that thread back around 2002 or 2003, not sure of the year. I had just bought a brand new BAT pre amp from Upscale Audio and was waiting for it to arrive when I discovered that thread. After reading it all the way through I was hooked, I flipped the BAT without ever unpacking it and a VAC pre amp that I had and bought a Syrah pre amp. I don't know how many times I posted in that thread but I know I was in there, plus I read everything I could about 6SN7's. I ended up with a pretty good stash of them, as well as W.E.350B's. The magic combo was 350B regulators, Tung-Sol 6SN7GT black glass, Bendix 6106 rectifier, and W.E. 417A in the phono section. Just gorgeous sound! My Supratek Pinot phono stage is in transit from Australia right now. But I have no idea when it will get here as Mick gave me no shipping info such as tracking. He isn't big on communication which is a bummer, maybe he is really swamped? I don't know.
I really wish I could read through that regulator thread that was takin down, I missed out on that one.
