In my observations about the SEC 2006 I associated the high-end industry with a strip join. Continuing this thinking I have to admit that Srajan Ebaen’s 6Moons.com site remind me a strip join with inflatable robotic girls. The all girls there ar...

It is very much might not be a false lead. I did not read further the article but on the first glance there is nothing wrong with that amp – it perfectly maybe a good-sounding amp. It has what is necessary – no SS in output stage – a big must fo...

I have a preference for making the power supply a certain way and using certain types of components. If I do that and am consistent about it, I can get better results from some of those old tubes than I can from the more recent types. But hearing one...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

I read it before but reading it now, after a few years again...

[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...

[quote user="RonyWeissman"]Hi, yes i agree that my solid-state amplifiers were not best choice for compressio drivers, they were my second amps when electricity was bad, otherwise I use a custom made 300B from La maison de l'audiophile for my s...

[quote user="Romy the Cat"]Tax what are you willing to accomplish by DSETing Avantgarde Duo? As far as I can see in any playback action and decisions it shall be a straight line of sight to some kind of objectives. What objective you have in your min...

Decoud (and others), where do you source big Nichicon caps, pref. in EU?I'm slowly preparing to attack a Staxquiades - a mastodont Milq inspiredamp to power Stax headphones (PP 6E5 DC to PP 2A3/300B/EL34). I need 10.000uF/500V and 10.000/350V caps.Mo...

[quote user="skushino"]So next week I will broaden my playback experience by adding my new 90wpc PP mastadon, and Romy's approved Lamm ML-2, in addition to my current DRD-300B amps. And as a personal favor to the readers at ...

Some facts:The Japanese horn scene uses colored amps like 300B and prefers to buy Japanese amps.American horns are mostly slightly modified pro gear, quite a bit away from the price range Lamm has in mind, so the market there is not larger than that ...

My experience is limited, but I tried it a few times (300B, 845, OTL ...) with 8 ohm Speakers, 92dB and a crossover, which is simple and never got a result which was close to a high sensitive speaker (98dB ...), no breathing, no air, Headroom was lim...

Yesterday a local hi-fi guy invited me to listen his new speaker. He picked up Altec Model 19 - I am known not to be a big fun of those speakers but they have own sound in the scale of non-demanding, off-the-shelf monitors. Upon expecting the speaker...

are you asking if i like higher impedance tubes with my drivers i have always love the sound of imac tubes round plate triodes !!! i change amps alot right now i im running 75tl amp for highs and a 300B for bass drivers . i hope this answers your q...
|
|
Agreed, not really knocking it, but I've used a similar/same input/driver on the 300B and the results were not satisfactory in my view. I think the view of using premium and exotic parts got started years ago... where people wrote that due to the si...

[quote user="drdna"] You had described the Melquiades as a "reality Reconstruction" amplifier. In my mind, I have always associated the unpredictable quality you describe with a "closer to reality" sound in my system. [/quote]
Well, I might ...

No. You are wrong. Harmonically, my SET is quite superb using either 300b or 811 I have unfettered access to the music in it's entirety. Transformer cores just distort the signal. Why on earth would I want one?

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

|
Oh well sorry for the false lead, you are probably right that there was just something falty in my 300B but at least I found an amp that I really like.Since i have two outputs on my preamp(placette) maybe i'll look around for a cheap flea-power tube ...

For anyone who's interested, I run my SL600s with a Rotel RHB-10 power amp, very successfully, I think. I tried them with a number of SS amps, and none of them did the job quite like the Rotel.(I did buy a tube/valve amp for my main system though - a...

You can eliminate the driver stage and drive a DHT in just one stage, because your source or preamp is sand based and has plenty of current drive.Page 10 of the PDf showed an example of driving a 300B DHT to full output with just +/- 4ma.http://www.t...
|
|
I agree that it is difficult to extract the color of the DHT from the 300B and indeed from the circuit used in this experiment. It would be good also to listen to some IDHT 300B amplifier.
However, there is something to be said for the certain ...

[quote user="cv"]…. I'm not sure I believe the overall hypothesis, I think it is more a function of the particular high/low impedance tubes he was writing about (300B, 10, 45 etc). But how this translates to neutrality above "levels 1 or 2" is anothe...

In the TAS that I bought because the Lamm ML3/LL1 review I found Jim Smith add about a new Engström & Engström Lars amp from Sweden. Jim tells the story about the Engströms and about the 20 Lars’s rules that reportedly assure “good sound”. Th...

Hi Roman, hi all... intriguing post and interesting questions, as I've been for about 20 years a triode and, before, a tube user and a glowing-in-the-dark maniac.My experience...I purchased - years ago - an Hiraga 20W which I used as a bass enclosure...

Thanks, Brad, interesting feedback about the Cessaro.
It hard to look at bass within the show’s hotel rooms but since Cessaro use “closed bottom” topology for their LF solution it always, at lest in my mind, will be a room for improvement in Cessaro...

I got my pair of F120A by-the-book bookshelves a few weeks ago and yes, in the beginning they were very much "compressed" sounding. Things improved a bit over time, but the low treble (which gives instruments their "color") is still recessed. So I ...
|
|
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...

Scott, my apologize, but issue of low-power does not have any relationship to the problems, you have described. The problems could be located in the following areas:- high output impedance of the last cascade, and amplifier in g...

Well done that man.

Years ago, when I visited the Cogent guys, Rich was working on one of their big drivers. The diaphragm was big and even thick and heavy, as compression driver diaphragms go. Of course they used 300B amps, and the bottom end had the "sewer pipe" type ...
