Whonna to drive dead woofers with single ended triode? Get the Bell Laboratories 320A tube.
The 320A Vacuum tube was designed for use as an oscillator, modulator, or amplifier at the higher power levelsand high frequencies.
Filament ratings: 35 vol...

Jim,
It is miniature tube that can handle 8W on plate!!! Still the most interesting it’s sound as triode. If you look its internals constriction then you will see a pair of huge “plates” and a large space for the “electron cloud”, it kind of in a w...

[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]
That is so cool that you...

[quote user="drdna"] It might also be instructive to have Joe visit Boston and listen to Romy's system, but I bet he would not go either. [/quote]
Probably, it would be instructive but I really do not want it to be as some kind of competition betwe...

There is a tube out there might be a good candidate to drive ULF from DSET
http://tubedata.tubes.se/sheets/127/7/7242.pdf
It is a low voltage triode with 100W on plate, 9 times gain and 80R plate impedance. 3 of them might form a...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

Paul,It would be improper for me to write down what I have worked on over almost 40 years in the telcoms business. WRT a CV for example, I have in the past written it all down and the reviewers do not believe it. Eventually, i stopped bothering abo...

Perrew,I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section com...

The references to inertia and lightness are not to do with how a DHT works electrically but to do with how sounds reproduced by them 'can' be ie without smearing or overhang. Its a characteristic I hear in live unamplified music and one that is endea...

[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]BTW, I have a incredibly accurate record of sniffing those thoughts. [/Quote]Thought sniffing is precisely the problem. Too much thought sniffing.You have not heard Mangers, Aporia, or Loth-X speakers yet you thought sniffed yourself into an i...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

[quote user="JJ Triode"]I listened to this talk up to the beginning of the question-and-answer session. I am surprised that this method would really capture the essence of Romy's almighty DPOLS condition. It seems to me that Robbins is very much cent...

Without completely understanding the post, I listened to all the samples (which by the way, will play immediately without doing anything if you have a mac...oops!). I first ran the files through my main system (there is a laptop + DAC associated with...

[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 to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I thought that I get use t...

[quote user="drdna"]But how can you make the Melquiades as a DHT amplifier? I do not see it. [/quote]
To make Melquiades as DHT is very simple juts use DHT output tube. However, if DHT idea does make sense then I think the diver shell be DHT as well...

More technical data :Designed around the Altec 288 driver

[quote user="el`Ol"] 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 ...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

I was looking at my recent observation that smaller anode makes better HF sound; better intimacy of sound and better articulation of detains.

Paul,
The idea of the not threaded forum is good that it is always there is opportunity to go back to all there and update own views, or to extend them. In many moths/years when the ML2 stop be a novelty for you, you might return to this thered and ...

Hello,
I've never had an SET amplifier in my system. Having high efficiency horns (106 db on average down to 100Hz ) I have tried a number of solid state and tube amplifiers, and I am aware of their sound in my system. ...

Romy, Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Your first ...
