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.

Other than the Elrogs I am not aware of any other tube that has been an issue for the Frankenstein amplifiers. Due to its thoriated filament different parameters were necessary for the Elrog 300b that deviate from the Western Electric standard.

Charles,

Not problems but perhaps shortened tube life?

Okay I see your point and that is a valid question.

I've just ordered a pair of Franks and am also worried about tube issues. Not sure if Takatsuki will last long enough. :)

By the way, in the review by Dick Olsher, it states that Franks are easy on 300B and the anode dissipation is only 25W. Strange...
