Elrog 300B vs Takatsuki 300B tubes

Hi Joe,
I don't hear a difference in sonic character at all and I was really listening intently for any changes. So, none that I have noticed. 

Markus, for a tech this is very simple and straight forward. The resistors are right there and very easy to remove and replace. It took my friend 5 minutes per mono block to complete the job. Fortunately the Frankenstein is easy to work with,ample space and few  parts (very uncluttered ). I used Munford 1.2K ohms/25 watts,  2.50 dollars each(1 resistor per mono block ).
Charles, 

Mundorf not Munford, darn auto spell!

drdavid..i have Psvane WE 845s and 300b tubes and could not be more happy with their performance. sorry about your experience with the Royal Princesses.I used mine for a few years and never had an issue. i still have them as back ups..Anyway....the We's are just superb..

Calloway, 
I had a borrowed pair of Sophia RP  in my amplifier for several weeks a few years back and they were very good sounding although not as good as the Takatsuki.  So what you write is high praise for the  Psvane W.E. Replica 300b. I use W.E. Replica 101D  my Line Stage and it's a superb sounding tube unquestionably. I've heard their 845 and it was also superb. 
Charles, 

I use a Quad set Takatsuki 300Bs and can honestly say they are as good as it gets--I would've gone for the Elrogs ( I replaced  stock EH's also excellent tubes) but at the time the reliability of the new E's was troubling 

However  I see that issue seems to be rectified and the brand getting good kudos from current owners. I'd suggest Audition both for any decision.

Good Listening
