el 34 vs kt 77

I have a Rogue cronus with kt77 tubes. What difference would there be in the sound substituting el34's for them?

I have Dodd 120 wpc MK II monos. I currently use Sqvetlana Winged C throughout the output stage, and Tungsols 5671? in the splitter/driver stage.

The JJs had a lot of QC problems, including thin pins, before they got their act together. I have some, and they aren't really in the same sonic league as the Genalex, IMO.
