Yep The same.
They used to be marketed in the states as Svetlana until New Sensor some how copped the Svetlana name.
IMHO these are among the best new production power tubes out there.
Peace
Yes sir, those be the ones!.... Except I absolutely love the sound of the SED EL34s running in Class A. Gives the Marshall grit but retains that beautiful smooth Boogie sustain. I recommend these tubes, definitely.
