Here’s a quote from Aaron from the He1.2b thread:
“Using the Mullard and Valvo (Siemens) 12AX7's in the GES instead of the stock Tung Sol 12BZ7's has greatly improved the tonal output overall”

I believe the 12BZ7’s were the upgrade tube Woo offers.
You can use 2 matched pairs to increase the number of possibilities. Trying a good vintage pair on the last stage should have the greatest effect on the sound.
