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.

Almarg,
I forgot to tell you what a great asset you are to this audio community with your technical knowledge and easy to understand answers.

I thank you, Sir

I agree that George Lenz has been very helpful here in working toward a solution for those Frankenstein owners who would like to use the Elrog tubes.

Hi Rob,
You can use ER300B in the AN Kit-1 without problems...
Because it's a kit I think You should have minimum skills at soldering and assambling. Thats why i suggest to add an additional resistor of 100Ohms(min 2W) between the paralled 1.5k Kathode resistors and the heater pin, so You get 850Ohms cathode resistor at all...resulting more gentle operating conditions.

Best regards, Matthias

Hi Robert (Rwanda),
I could not find schematics of the Cary 300 SEI...But the description says 15W(!!!) watt per chanel (out of ONE 300B!).
May be, they use class A2 conditions (driving the tubes to positive grid voltage) or they use the absolute maximum operating conditions (450V/80mA) to get this 15W...
If this amps have a bias control and You can regulate the bias to 70-80mA, ER300B could be used successful. But I can not suggest this at the moment.

Best regards, Matthias
