The Czech Republic-based Emission Labs Company introduced their new replica of famed AD-1 Triodehttp://www.emissionlabs.com/html/club/labreport.htm
It looks like Yamamoto, Japanese amplifier manufactures has made an amp with this tube: A-06Shttp://w...

[quote user="enjoy_the_music"] Well I am fairly new to active speakers. I've been in contact with Merlin and Guy in the UK about these type of speakers and their experiences. I'm just taking it all in and then going forward making a few mistakes and ...

…and I hope you did put your ET-703 tweeter in a time aligned position, did you?
The AD1 tube was one of those original “better sounding” triodes. I have a quite few of them; in Telefunken 1936-139 radios (I have 4 or 5 of those radios them in my st...

Yep, you re right, the Yamamoto A-06S is SET, I did not read it carefully and I was under presumption that A-06S is PP monoblock. Good for Yamamoto! The only amps I heard with AD1 were PP. Somewhere in the very end 90s I shortly was exposed to i...

Hi,I have just received a Yamamoto A-02 amplifier from Shigeki. It is a 2A3 / 45 switchable amp, not available in the EU. It is supposed to be Yammies top amplifier. I bought it in JP and sent it to Shigeki for new 230V transformer...

In the thread GM70 vs. 6C33C two year back I have written that the only tube that I would like to trey in Milq besides 6C33C would be YO-186.
I am not sure that it might be a right direction or even interesting direction but I picked yesterday a par...

[quote user="Romy the Cat"]http://www.goodsoundclub.com/pdf/YO-186.pdf[/quote] Here is the lit sucker that I told you before. It is Russian impersonisation of Telefunken AD1. It was made from 1932 to 1963. It is smaller than 2A3, the size of the larg...

[quote user="Gregm"] We may postulate that … compression is beneficial for soundstaging.[/quote]
... You are right and it is very simple to witness. A high dynamic range creates less soundstaging and more imaging. Higher compression kills imaging an...

Yes, it is true – it looks like a move toward my Audio Demoronisator

However, I would like to see what and how Fenice does what it does. This new paper MF driver looks interesting. I ...

[quote user="DHT4ME"] This is true. It comes down to thermal cycling. I love the #26 tube but it is real hard to get quiet. It has a 1.5v 1a filiament. The heavy draw causes thermal cycling which is very hard to null out. There is also more rati...

Be careful to relieve me if I am not impressed, many promised no one excelled. :-)
Chris, I do not think that you will see me to think about transformers for other channels. I do not think that what I do will be some kind of resolution for Amor...

I know – it idiotic even for my site but it us what it is. I do not think that I can generalize my observations as I have not a lot of experience with DHT tubes but one thing that I have been observing for the last week is really arouse my curios...

Since I am now in the Super Zarathustra conceptualization mode am paying attention to the hybrids out there.

Very wise, Roman... I - myself and my wallet - both must agree about your feelings and opinions... I've been into tube collecting since early '80s and what I guessed was dear (ITL 50.000 (about EUR 25) for an AD1 or "Luftwaffe" RE604 is now a TRUE ba...

Manolis Proestakis from Greek have announced his Anima Loudspeakers.

The lead came from Stefano Bertoncello's blog; the picture was taken from there as well.

[quote user="drdna"] Well, and I have a dozen of them sitting here next to my desk while I am building my Milq amp s-l-o-w-l-y so I guess I will discover my audio intelligence level sometime after the New Year.[/quote]

I was pointed at a site where people debating the subject of 2A3 vs. 45 vs. AD1 vs. RN604 vs. YO168. Naturally they pointed out to my site, bringing my articles from this thread on the same subject as some kind of reference.
I read their comm...

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

[quote user="de charlus"]Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far fro...

[quote user="Wojtek"]I assembled SUN 2A3 amp for my friend and found it to be quality kit and very easy assemble. Kit was old .I think late 90's so maybe quality deteriorated since then. I have variety of 300b Czech tubes and (Eml 300b , KR 300...

I made experiments running HF filaments from dedicated Hammond 6.3V transformer vs. lifting ground on my 6.3V IDH filaments. I did not listen Sound but rather measure the noise – the result was identical. In the best cases I was able to get 0.63m...

[quote user="Romy the Cat"] When I said four transformers I meant that I can see 4 type of the tubes. The 2A3 with 700-80R on plate, YO186 with 1200R on plate, the 45 with 1800R on plate and 10Y with 5K on plate. Hey are requires different transforme...

It turned out that I end up with 4V tubes for MF channel and am running my YO186. The 2A3 tubers I kind of have left on peripheral of my interests. It is not the 2A3 tubes are “bad”. I did not go deep with 2A3 and did not try their expensive sin...

Ok, I do not know what it was: was it DHT, was it 300B, was it some other specifics of this given amp or whatever… but those two aspects that I named: intentional density of colors and randomness of pace are something that I would like to exercise in...
