Elrog 300B vs Takatsuki 300B tubes

Hi Joe (Snowpro),
I have to confess, the more I listen to the Elrogs the more I'm in near awe in what they offer. If they prove to be reliable and durable I'll consider them one of my best audio purchases ever. For people who own a high quality 300b amplifier and cherish natural/organic realism of sound, this is your tube. Music is so alive, present and engaging emotionally with these tubes in use. Honestly striking in my system. It's very difficult to bring a listening session to a close. Matthias, you and your colleagues did a fabulous job with these tubes. Thanks.

I have been a silent observer of this thread. After hearing all the pros and cons of the Elrogs I contacted George Lenz and purchased a pair.

Like many of you I own the Coincident Frank II's which are just superb amps. Can't believe how quiet they are and how cool they run. What a difference from my Joules!

At any rate I wholeheartedly agree with Charles that the Elrogs are something special. Unfortunately after about 100-150 hours one of them crapped out. George told me that these were the new improved versions suitable for the voltage levels of the Franks but apparently that was not the case with mine.

George was very gracious about returning them and currently I am waiting patiently for a replacement pair. They are supposed to be shipped to George on 11/23 so hopefully I will have them soon.

Hopefully the replace to pair will be more robust. They sure make listening to music a joy. Just not the same without them in the system.

I have also been a silent observer of this thread. I own a Lampi SE Golden Gate DAC and so have been very interested in what tubes might be best for me. today I called George Lenz and ordered the Elrog 300b's. he was very helpful over the phone.

currently I have the Psvane 300b WE replicas, the Psvane 101d WE replicas, and the National Union 45's. i don't dislike any of them. I was seriously considering investing in some NOS vintage WE 300b'S but the big dollars caused me to look for a better alternative.

I appreciate all the great information shared in such a helpful positive way in this thread. I admit some/much of it goes over my head but ultimately it did allow me to be comfortable going with the Elrogs. I look forward to enjoying them.

Scifi and Mike,
This is exacly why I always mention/address reliability when discussing the Elrog ER 300b. Scifi, Snowpro, Brownsfan own the same amp as I do and are hearing the same results. The same seems the case for Lampizator Big 7 and Golden Gate DAC owners as well. If the Elrog engineers have corrected the failure issue then a superb tube is available for us to treasure.
Scifi, I wish you the very best outcome with your replacement Elrogs. You are right, the sound isn't quite the same without these tubes in use. I'll continue to post periodic updates on my Elrog 300b replacement tube experiences. I feel like a guinea pig(early adopter)) in regards to these new products, but that's my willing choice.

Scifi,
I've read nothing but high praise concerning the Joules OTL sound quality. I assume your speakers are pretty efficient if you're able to use the much lower power Frankenstein MK II SET.
