Elrog 300B vs Takatsuki 300B tubes

I have addressed the over voltages and under voltages of my incoming power by using a PS Audio P-10 regenerator. I think it's a great thing. In my area, the power was measuring anywhere from 116v to 124v. I'm not associated with PS Audio in any way but the P-10 really works well.

Snopro, how many hours did you have on both pair of tubes when you compared them?
The reason I am asking is that it's crucial.
Takatsuki requires 150 hours of burn in. 100 hours minimum from my own experience with many pairs of these tubes in various systems. Until 100 hours they could be a hit or miss. When they are fresh they can even sound like 200 dollar tubes, nothing special. I'd say 150 hours is a must for any critical listening or comparison to other tubes.

I've asked about Elrog's burn time previously but I don't have an answer at the moment. Several people reported they sound good right from the start. But from all my experience with various 300B tubes all of them require burn in. PSVANE T2 requires 300 hours before critical listening or comparison to other tubes, Takatsuki - 150 hours. Elrogs probably some time as well. TJ Full Music SE may sound nothing special until 60-70 hours but full break in is longer. I don't believe Elrog has 0 hours to be broken in. I would give it 150 hours to be fair.
Also, amps that have manual bias, like one of my amps, should be biased for any new tube installed otherwise sound comparison doesn't make sense.

Dracule1, please keep us updated on Elrog in Lampizator Golden Gate! Did you have a junior model Lampi before?
My Lampi came with EML 45 Mesh.
I might try PSVANE WE 101D replica on it and Takatsuki but this will not be any time soon, need extensive burn in on them all to be meaningful.
I am also with you on passive preamps :) I used to have several, from resistor based attenuators which depended too much on impedance matching and cables to many transformer based volume controls which were so much better in sound and so much easier in matching. I now use either Coincident Line Stage with transformer volume control or Kondo active pre but I still have a current model of Django TVC with Silk Audio transformers.

Hi Dmarkov,
I have my Taks almost 2 years. They are well broken in and the Elrogs had less then 100 hrs.
They are both excellent tubes. The Elrogs give me a little more body to instruments, which I like.

Dmarkov, I will keep posting. I have EML 45 and RU4, Psvane 101D and 274B replicas, TJ Full Music 300B SE, Elrog 300, and Brimar 5Z4ZY. I have the Takatsuki 273 on the way.
