Rodman or anyone else, have you actually substituted 12AT7s for 12AX7s or other swaps mentioned in the links?
It would be great if we could swap tube types but the Tube Store writeup says:
"These substitutions can also work in home audio amps, but we don't recommend trying this unless you are having trouble finding the correct tube type for your amp."
