Elrog 300B vs Takatsuki 300B tubes

Yes, the Takatsuki shouldn't be a problem at all, it adheres to all the Western Electric 300b specs. The Elrog with its thoriated tungsten filament has some deviations from the W.E. standard. I received some new recordings and listened to music for about 4 hours last night. I just love what the Elrog is able to do. There's no thought of audiophile /analytical evaluation. Nope, you are just engrossed in the music being played. IMO the sure sign of a good audio product.
Charles,

Dracule1, Elrog is the best tubes that I heard on Lampizator. I don't even need to A/B with Psvane 101D 1:1 replica to know it is way better. Psvane has been a great performance tube and was my reference before.

Wyan, that's some high praise for the Elrog. I really like what the Psvane 101Ds do on the Golden Gate. Let's hope Elrog makes a version that can handle AC filament supply.

Hi Dracule1

>Let's hope Elrog makes a version that can handle AC filament supply.

ER300B can handle AC filament supply...the problem is the residual hum...depending on the speaker sensitivity. Thats why we recommend DC heating.
The problem is the very small thermal mass of the very thin filament wires, necessary matching the heater specification of WE (5V,1.2A) using thoriated tungsten filaments (Filament temperature is about 1650°C instead of about 700°C).
We could build 300B using oxide coated filaments, but this would be another (boring) copy of the 300B only...
Using thoriated tungsten is the reason of sound improvment, because the behavior is very different.

Matthias,
I find it quite interesting that the filament material so positively influences the sound quality of a tube. All I can do is confirm what I'm hearing, beautiful music reproduction.
