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.

If the power supply is outputting somewhere around 425V that would mean the 300b tube would see a more conservative 325 to 350v acoss the plate depending on the cathode resistor value.

Charles I think Doug has the test equipment to measure these tube paramaters on his test bench. Its nice to have a Techy friend in the audio business.

Jeff,
It would be enlightening if he can measure plate voltage and other fundamental parameters.

Charles,

Does your MKII incarnation of the Frankensteins have both an HT fuse and a second AC fuse?

It is my understanding that the HT fuse is intended to protect the Frankensteins in the event the 300B tube fails.

I am curious whether the HT fuse blew when your 300B tube failed?

Wondered if anyone can chime in on how the Elrog would be in a Cary 300SEI? I believe I have read somewhere that this integrated pushes a 300b a bit...or could I just adjust the bias down a little to try and compensate? thanks
