Here's my stuff:

ENGL E530 rack pre ( 2 12AX7 )
VHT 2/90/2 power amp ( 4 KT88, 2 12AX7, 2 12AT7 )

Right now, based on recommendations, I'm going to get:
4 Ruby Winged C KT88s
2 Shuguang 12AX7 9th gen
2 Tung Sol 12AX7 re-issue
2 JAN 12AT7WC Grey

Is this a solid set up, or do you have any other recommendations?

I will be emailing Doug and getting suggestions from him, but I wanted to get everyone's input.

Thanks!

an alternative to the 2 Shuguang 12AX7 9th gens you could do 2 Penta 12ax7's. They supposed to be warmer and more articulate. Still chinese but a step up from the Shuguang's. I got two of each in my 5150II and sounds so brutal. Ask Doug (he is the man!!) if he would recommed them for your amp. I ordered a full retube of what he suggested and my amp has never sounded this good. I have a Powerball I was about start using..........not going to happen now. My 5150II now eats the powerball alive, and I didnt think that would've been possible.

oh, and I'd say its a very good selection thus far, still ask Doug though.
