Elrog 300B vs Takatsuki 300B tubes

Gary
Unfortunately part of the problem is Elrog has much more demand for their tubes than they ever had anticipated. They just aren't able to keep up with all of the requests, this is really a small specialty German tube making manufacturer. Gary. Try tubesusa.com, this was my source for Elrogs and EML. Very good customer service.
Charles,

This again illustrates what I've always known. No matter how impress one person may be with a particular product there will always be someone else who finds it disappointing. It's just the way things go with subjectivity issues.
Charles,

Fortunately, as I have commented previously, I am very happy with the Takatsukis.

To my ears, the Elrogs are just outstanding in the Coincident Franks. They are much better in essentially every respect as compared to the Psvane Ts. Previously, I had found no preference in comparing the Ts to the TIIs, and found both of them superior to the Shuguangs. I have not had the pleasure of auditioning the EMLs or Taks.
My advice to other Frankenstein owners would be to give the Elrogs a try. I seriously doubt you will find anything better based on my experience and that of Charles. For owners of other amps, your mileage may vary. The good news is that we have some wonderful tubes to match to our amps and individual tastes.

Hi Charles1dad,
With my HUGE respect to you, this is not what I wrote.
I reported a case where with a particular SET amp Elrog was not just unsatisfactory. It was most probably not working properly as the sound was much inferior. It was not a matter of preference. The testers have huge experience both listening and building amps, I have not a slightest doubt in their assessment (there were 2 people, I have feedback from one).
In the second case I reported, it was indeed a matter of preference and not towards Elrog. And the man owns all these tubes, it's not a quick AB test. The SET in this case is also not Frankenstein MK2s. They system is very high grade, higher then mine and mine isn't a toy either.
The Elrog is not a drop in replacement for any 300B tube. What's called 300B tubes these days is a mix of different designs and even specs and this does cause problems in some amps. Several amp designers discuss or mention this. I could drop names of particular tubes here but I won't :)

Old WE's are not the same as new WE's and various batches may have different qualities too. I only heard new WE's, never the old ones but did several times, one pair is still with me.
What's very important is that Elrogs do work wonders in Frankensteins and this is key and very valuable info.
I am going to be more careful with other amps.

I am extremely grateful to you for making me replace 101D's in my Coincident Line Stage with PSvane WE Replica. I also replaced the fuse with AH. I totally confirm your findings there. I also paid attention to Star Sound and Tripoint type of products and am trying both with good results.
