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 Rfprice,

No, we do not offer unlimited warranty!
Our warranty covers 2 years on materials and manufacturing and a half year for the emission.
It is a matter of grace for a new product.
It's very annoying if a tube fails, but it can happen. It is completely normal with such a new product. There are covert and late visible problems...And we can not by hundrets of different amplifiers to test the tubes...
But we can replace failed tubes by obligingness ;-)
Btw, 90% of all delivered tubes are working well.

Amplifiers with gentle/conservative operating parameters are probably no problem for the Elrog.
One of my Elrog 300Bs failed more than a month ago and I had to ship my pair directly back to Germany after talking to Gary in Trueaudiophile. Elrog initially refused to replace my pair although I had several days left on my warranty. Gary has been following up with Elrog to change their decision. I have been waiting anxiously more than three weeks now. So, this is such a relief that Elrog finally stepped up to take care of their products and customers. I love my ER845s and that is why I bought ER300B. I even left very positive comments for ER300B in this post. Great that Elrog didn't betray their fan...
Bhchung, I also purchased my tubes through Trueaudiophile, and am awaiting instructions about the return process. I would of course prefer to work through the vendor, but if that is not possible I am willing to deal directly with Elrog. Matthais, how should I proceed?
Hi Matthais,
Same question as Brownsfan here. What do I expect from here? Elrog already has my pair and warranty information.
