Elrog 300B vs Takatsuki 300B tubes

Hi Pani,
I had a FW J2 amp as my back-up amp. I use Frankenstein Mk.2 300b's as my main amp.
The J2 is a very good amp, detailed, very open, fast, great bass, but the Franks are more liquid and sound more natural in tone and timbre. 
The J2 had a slight grain compared directly the SET amp. Don't get me wrong it is a wonderful amp, but the 300b's push my buttons more!

Hi Elrog,

Unfortunately, one of my ER300B started failing again.  This is a revised version that replaced my original pair last August.  It keeps cutting out and making noises. I can turn amp off and take tubes out for a while and then it works for a while and quits again. Sometimes it won't even start up so it is definitely bad.  I didn't use the tubes much at all after I received the replacement pair last August.  So, they have less than 100 hrs.

I have been trying to contact Matthias as he instructed in August but haven't received any reply so far.  I hope someone in Elrog can take care of my case.  (For the record, I copied email exchange from last year).

I think ER300Bs (with ER845) are the best sounding tubes out there.  I really hope that the company can back their products and take care of their customers.  
 
Let me know how I can proceed to get replacement tubes.

Thanks.  
Byung

Sorry to be digging up an old thread, but this is the most in depth information regarding the Elrog 300B that I can find.  

I am interested in trying the Elrogs, however I am curious to know if there is anyone out there who has had the 300B that has not failed?  If so, what amp are you running them in and what are the operating parameters driving the tubes?

Thanks,
Ed

Does anyone have recent experience with the Takatsukis?  I have already had two pairs of the Sophia Royal Princess 300Bs die on me, so I am steering clear of the Elrogs for now.

Specifically, I would love to hear how the Takatsukis perform in any Audio Note amplifier.  I have ordered a pair from PriceJapan, but apparently there is a two month wait at the moment.  I have sold my low hours pair of PSVane WE Replicas and have my Shuguang Black Treasures up for sale.  Both of those will help pay for the Takatsukis : )

So, for now I am back to using the stock tubes.  They are good but don't have the texture, detail or colour of the PSVane Replicas.  I figured that this is going to make the Takatsukis sound even better!  Stepping up from the Replicas wouldn't be nearly as much of an improvement as coming from the stock tubes.

Anyway....just waiting patiently for the Takatsukis.....is that the FedEx truck that I hear?  No, just some car passing by : (

Must be patient.....
