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.

Mk,
How about Wyetech Sapphire monoblocks?
18wpc parallel 300B SET self-biasing conservatively run.
Will your tubes work here? Would love to try 'em!
Hi Fla,
I have read the article in 6moons and the description on the manufacturer's site. Very nice amp with a lot of effort in details (huge capacitors in HV supply, dedicated heater supplies for each output tube, smart solution for changing the gain, switchable output impedances from 2 to 16ohms).
Very gentle operating conditions...30W dissipation per output tube only...So "Globe Mesh Type" 300B can be used. This tubes don't like stress also. This amp was build for ER300B ;-)
For best results You should order a matched Quad.

Best regards, Matthias
Fla,
Based on Matthias's favorable comments you're fine with the standard Elrog ER 300b.

Hi Matthias

Thank you for your help. I called Cary...and the newer version of the 300SEI actually runs 11 watts (they say) and 400V on the Anode - 35 watts ...so if I understand correctly the ER 300b should be able to handle this easily.

Again many thanks

Robert
