I can't be of any help but congratulations on your purchase. 
I was just over at Manley's site and they've completely redone everything.

I found that replacing the 12at7 with 1961 Brimar cv4033 from Tubemonger made a great improvement over the EH stock tube. Smother, more air and bettter mids. $45 each with 10,000 hr life.  I'd like to try the Siemans they have too, more detailed he reckons.
