Don't forget the same tube 6C33C was used on Russian ICBMs guidance systems
Tube question: any sonic difference in 6SN7 vs 6H30 vs 6H80 in the amp's signal position?

Reason I ask is I just received a new-to-me BAT VK-55, and it has 6SN7 tubes in the signal positions, which is also what the manual references as the right tube, but the Stereophile review, in the specs page, references 6H80s in the same position, and VK-55SE uses a pair each of 6SN7s and 6H30s.
BAT output tubes are 6C33C-Bs, so no tube rolling here, as it appears Solvtek is the only manufacturer of this style tube. I am wondering what if anything I can do with the signal tubes to help improve clarity of higher frequencies?
