Elrog 300B vs Takatsuki 300B tubes


Has anyone heard the Elrog 300B tubes ? I read an article which mentioned that the Elrog 300B delivers 15% less power than a traditional 300B tubes. Can anyone confirm that it is audible ?

I am choosing between Elrog and Takatsuki 300B tubes. I would prefer the Elrog because it is cheaper and supposedly wonderful but if it really sounds less powerful then I have to rethink.

Dracula1, To be clear the first set didn't fail. George took them back for a new set that better matched my Frank's higher voltages.

George is great to work with and he stands behind his tubes!
Here is his website: tubesusa.com
Common autocorrect mistake, LOL. I'm not a vampire. I swear! Dracule means "son of the dragon".

Anyways, I'm glad George was able to accommodate your needs. I didn't know Elrog made higher voltage version.
Dracule1,
What George will attempt to do is match the Elrogs to the operation points of a particular amplifier. This is done with the cooperation of the Elrog factory. George's tubesusa.com has been mentioned on this thread several times. He has stood behind his customers with strong support.

Snopro(Joe) glad you received your replacement Elrogs. Your Takatsuki-Elrog comparison matches my impression. Both on their own merit are excellent. Hard to believe but the Elrog is more natural and musical than the superb Takatsuki in my system (that's some feat!).
