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?

These are used as driver tubes in my 845 SET monoblocks, so your results may vary. To put it mildly. Dave

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.
