Hi King,
Not sure if you caught this great thread (http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1112733965&) on tuberolling in the Supratek.
I have a Chardonnay that I purchased last year. After some of burn-in with the stock tubes, I found the sound a bit thin and subsequently did some tube rolling per the experience and recommendation on this thread. After trying many different 6sn7s, and regulator tube varieties, and also many different permutations of each, I arrived at my current tube components which are also, BTW, sited by many on this thread! (National Union 350b, Tung-Sol 6sn7gt RP and a Bendix 6106). With this line-up the sound is big with a lot of weight and substance.(Brimar CV1988 and Kenrads are also quite nice in the line stage.) I have also tried the Philips metal base GZ34 but find the 6106 provides a more focused presentation. You should give both of these rectifiers a try and see what sounds best in your system.
