VHT Pittbull 45 pre-tube lineup?

[JTyson]

I have a good friend with a Pittbull 45 (class A) and he has read somewhere that there is an order of a combo of sovtek and chinese tubes in the preamp that will yield optimum results from V1 on..
He has the sovtek and chinese tubes, but cannot remember the order, anyone got any input on this??
Thanks

I have one, I'll take a look and get back to you. I bet Dougs Tubes would know, as well as the dudes at the Fryette forum. http://www.fryette-users.com/forums/index.php
