Maybe this is the correct place to ask. I'm new to the tube world, and trying to figure out what type of preamp tubes i need for my Diezel VH2. After doing some digging online, it sounds like I am needing the Ruby 12AX7AC5 HG+ for my V1 and V2 positions. And I'm thinking the Shuguang 12AX7B for V3 - V5. Does this sound right?
I have JJ KT77 for power tubes.
Thanks!
