[quote user="Romy the Cat"]Celsius, I do not know what CCS you impended, did you drive 6e5p’s plate with constant current source?*1 I also do not know/like 6e5p with battery bias. The only application that I find 6e5p suitable was the Milq-style bi...

I was listening the Opera it last night and then returned back to the Prince Gremin aria – there was a true fascination HOW the Italian bass Ferruccio Furlanetto he did the celebrated Gremin’s story.

Tonight I recorded the Live Tanglewood broadcast with all Russian program:

Taras Oleynk aka “ML8” sent me a couple months ago his measurements of different driver line-level tubes including the Melquiades’s diver tubes – the 5E5P. I am posting his data here with his permission, including Taras’ statement that is JUST PRELIM...

Reggie, let to be clear that I use definition of kitsch in reference to audio installation. The Camerata as a cultural event is out of my criticism; in fact I applauded to what they did. The Camerata video did not bring me to the idea of perceivi...

I have received a few emails today informing me that this idea of a super high power low frequency SET would not be possible and it would be “pushing the things WAY too far”.
Well, perhaps…. I am not planning to build it but I would like to encourag...

Well, it took almost two month and much more money then I thought but I was eventually able to get very decent sound out of monitors. The SL600 sitting on my “fundamental channel’s” tripods did not do well as I told before and I was forced to s...

OK, let me to recall. We learned that the “hysteresis” (for a lack of better world) manifest itself on used tube only. Also, what I see in the images the one of the half of the used tube has more “hysteresis” then other. I think it leads to the follo...

After I post my above message “The Altec Idiot” deleted one of my post (perhabs more, I did not check) within the thread claming that “it had no intrinsic value whatsoever”. Ironically, I personally believe that that the deleted/vandalized post ...

This week Romy was kind enough to invite me over for a few days for some Apprentice work and philosophizing. As I alluded above, my Apprenticeship contribution consisted principally of moving some audio gear, searching for some esoteric stuff hidden ...

[quote user="Cosmos"] Anyway, as the description on our site on second paragraph says, the third 6C33 located at the back, is used as the pass element of the regulator (controlled by solid state circuitry) providing 220V with 100uV of random noise &a...

I have no idea why this guy is and what he says, I even have no idea of what language it is but here it is: the 6E5P-6C33C amp in PP configuration.

That is kind of mysteries to me and very none expected. From the people who use DHT I heard many stories that 2.5V filaments driven by AC are less noisy then 5V or 7.5V. That is kind of self-explanatory as with higher AC voltage the more noise. S...

[quote user="doug s."] if you have good reception in your area, the sherwood will be fine. but the sound is where these things excel, really. as they are so dirt-cheap, and even pretty-cheap when completely refurb'd, you owe it to yourself to a...

Paul, I do not think that “before or after RIAA losses” requirement has any merit as no matter what kind type RIAA filter is being used it always will lose around 20dB. I do not think also that there is a “safest path” or “reasonably affordable”....

The substitution of tonal semantics to visual semantics is well researched phenomena. I think Russian composers and musicologist in end of the 19 century of the 20 century went further then anyone else into the subject.
From an emotional perce...

Rowuk, first of all, I very much recommend you do not undertake the Paul’s advice and do not go for any implementation of bass with bigger drivers or more driver of different topology of bass section like OB and so on. For sure better bass would ...

Well, Brian, I do not think we here are in a competition whose way is more innovative, also the RX corrector do not use any air caps, and I do not know why you refer to them.
Unquestionably the idea to milk a transformer and to use its inductance to...

Since the electricity going better as temperature outside goes down I might begin to play and appreciate again some sting music. Lately, I bought 6 CDs and all of them turned out to be very interesting.

I recently dealt with two manufactures that produce music . I noted that both of them stated with good result but nowadays, years in operation, they produce despicable crap. This correlates with a famous amplifier manufacturer, very much not stup...

For almost a year I am in frustrated mental search for a properly performed “Andante e Rondo Ungarese”. This is a Carl Maria Von Weber’s Op.35, two parts little composition that in my view absolutely brilliant. It is collaboration with bassoon ...

We are talking about subjective reactions so there is no way to dispute either of our responses. However, I do see a disconnect between your statements that I quoted and your subsequent post. In the first post you were talking about the Queen of Spad...

Okay so I got the NOS Sylvania "Spring Top" dual filament 2A3 tubes and have been listening to them for a while, now I am ready to make a report on the tube.
The tube is well built and structurally sound. Tapping gives a very small "tabla" sound ...

The funny and poor Tuyen. It looks like another audio guy, as Russians says, “went over the hands”. The “went over the hands” is a very interesting Russian idiom that use very frequently apply to audio people. Years back it was once very deservin...

Eduardo,
Thanks for your thoughts and illustrations. I also do not feel that loosely-suspended very small metal cone might be a right solution for midbass. To develop LF you need pressure, pressure is surface by exertion – there is nothing els...
