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.

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.
Charles,

The Joules are a different kind of beast altogether. They produce voluminous amounts of heat given that they use the Russian 6c33b power tube and many of them at a time. You could literally roast weenies on top of that amp! LOL

They also have many other smaller tubes in the amp and require a variac and constant maintenance to keep the bias adjustments correct. Try to get service on them now. It is very difficult. BUT I'm not here to bash Joule because in the end those amps produce some beautiful music.

However with that being said, the Franks are just such a beautifully simple design. They are so darn quiet and run so cool for having a 300b in the mix. Of course it goes without saying that they create the most pleasant of sonic pictures. I have never been happier with a pair of amps!

Yes, my speakers are very efficient at 92dB but more than that they produce basically a flat impedance curve from top to bottom. They are the Audio Kinesis Zephrins designed and produced by Duke LeJeune. Duke is a joy to work with and together we plotted out the type of wiring I wanted in the speakers as well as exactly what compression driver would sound best. It was fun to have input into the process and the result has been outstanding.

As far as the Elrogs go, in talking with George very few of the latest Elrogs going into Franks have failed. He stated that aside from mine there had only been one other. Actually one of the tubes was just fine but George wanted both back so that he could replace them with a matched pair. George provides nothing but first class service and I'm hoping that this even newer set will result in many hours of happy listening because that tube is truly extraordinary.

Hi Scifi,
I agree 100% with your comments concerning Georgr Lenz.
Funny you mention Audio Kinesis speakers. Before settling on Coincident speakers I had seriously considered the Audio Kinesis Jazz Module speaker(92 db and 16 ohm load). Others that interested me were Horning,Ocellia and Tonian Labs Classic 12.1. I've always been very impressed with Duke Lejeune's contributions and demeanor on this site. He comes across as someone with class and integrity, which you've confirmed. No doubt his speaker is excellent in your system and mates beautifully with the Frankenstein amplifier. Scifi, lets hope our replacement Elrogs withstand the test of time.

Charles,

For sure let's hope that the new and improved Elrogs produce outstanding music for many many hours!!

I see that you have the matching Coincident Line Stage preamp. What can you tell me about it. If it is anything like the Franks it must be outstanding.

I am currently running an Allnic L3000 which is pretty darn good in its own right but I'm very tempted to sell it and purchase the Coincident. Your thoughts!

Thanks,

Scifi
Hi Scifi,
It is a terrific Line Stage, every bit as good as the Frankenstein. You can email me for more detail if you'd like.
