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.

Hi Bill,
My CSL is an earlier model than yours.  I bought mine new in Oct 2009 and very likely Israel has made changes since then is my guess.

One thing for sure, a 1 amp fuse makes far more sense than a 7 amp fuse for a Line Stage. Why would the CSL need a larger fuse than the power amplifier (Frankenstein )that uses a 3 amp rating?

Charles, exactly.  Those fuses are becoming frustratingly difficult for my old eyes to read.  I could not fathom why a pre would take a 7A.  Also, the filament looks pretty thin for a 7A.  I ordered a fuse for the CSL this morning.  Eager to see what all the fuss is about.

Bill,
I believe that you'll hear differences from the stock fuses very early on. It may seem amusing given it's a fuse with its thin wire filament  but it does really improve with burn in time. As always Bill I'm interested to know your listening impressions. Once you have it in awhile reverse the fuse direction. They are directional for certain. 
Charles,
