Interesting. with sealed 280 sq feet and 8 drivers per side along a long wall you very much migh be able to use a singe 6C33C. With proper loading, good trasformer, DSET and these drivers you should be able to get bass that I doubt you will be able t...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

[quote user="drdna"] However, there is something to be said for the certain magic that can sometimes happen with a particular device. The unpredictable transients and color shades add a sense of alive-ness that seems separate from the standard charac...

[quote user="nl"] Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, ...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

In this thread I would like to talk a bit about the practice in DSET driven multi-way horns configuration.
I have expressed my view that the architectural configuration that Macondo and Super Melquiades end up to be I find is the most interest...

I got a forwarded email today containing the Lamm Industry’s release notes about their new SET amplifiers.

[quote user="Romy the Cat"]Well, it might sound as a heresy to you, but I personally
consider the impedance curve is a bit irrelevant in this application. In this application
you need to care only about only 2 things: if you have enough power in yo...

[quote user="Gregm"] No-one is criticising the ML3 (amplification) product. We are discussing the concept and the applicability of such products, i.e. the ultimate limitation of an amplifier called upon to work from DC to daylight and, accordingly, d...

Hi Romy,
I am planning my own DSET build. I have based my speakers on your Macondo and
am busy turning MDF horns in my spare time.
Once that is over I will move onto amplifiers. I plan to build a fullrange Melquiades for a
friend and the...

Last night I was listening Zubin Mehta’s recording of Bruckner’s Symphony No.9. It was his first recoding from 1966 with Vienna. I am not a big fun of this performance all together but it has spectacular first movement. It played superbly slow and s...

CV, Good scenario as well but my leading idea is slightly different. I would like to keep any reactance from the path, would it be inductive of capacitive, to assure ultra fast response time. Basically I would like to maintain the MF amp as it used ...

I do not remember which one I used. I remember that I was deciding if to mount them on chassis vs. to have a small board with tube sockets under the chassis and bring the tubes through the chassis. The board mounting is better as it decuples the tube...

I do not know it is just Triamp or 3-chenal DSET by the direction is good. The amp was mentioned by Twogoodears on his blog.

Well, I kind of understand that my objectives for my “perfect” MF channel I have some irreconcilable differences. Let see:
1) No capacitors in signal path
2) Bandwidth restriction, allowing employ DSET type output transformer wit...

So, the first DSET is still downstairs on the electronics bench and I am back to work for a while, but not too hard and not for too long (I hope). I've added all the filters and checked and tested and changed some more things and decided that it was...

So, I have finally started testing a single Bass Cannon in my room.First, I had to get the rigidity as high as possible and then damp the steel ringing as much as feasible. I used butyl rubber/aluminium automotive deadener on the inside of the tube ...

[quote user="Jim Smith"]I've been following this line (mostly the big one) with great interest since it was first mentioned.It's definitely the most interesting high-efficiency horn line available, as far as I can see. I've been asked to look a...

Good concern, I had and have it as well. I do not have an answer at this point. It should be stressed that my description of artifact was just my specific description of THE artifact, the MF texture music had also a “face lift” - I just d...

Ok, I made some further experiments driving this time my S2 driver from Milq DH DSET. The hell of the sensitively - it was too much. So, I went for 4:1 inner-stage ratio. The result was very successful and the amp looks like was able to get more...

[quote user="Paul S"] Didn't you first become aware of MF "problems" when you got everything else working better via the PP2000, and the MF wound up dropping back to weak sister status with respect to system-wide PP2000 benefits? [/quote] The PP2000 ...

Yep, it looks, like very close to “it” design-wise. http://www.studiomaudio.info/loftinwhite.htmlIn the way this amp is one of the manifestations of Loftin-White DC-coupled but it has some own things. The driver stage is the Melquiades Tube to k...

Hi Romy,i want to use the 6E6P-DR (triode mode) as driver in my tube 45 amp.I use a D3A (triode mode) with Anode choke at 180V, 12mA. Grid 2 is connected via 50 Ohm resistor to anode. Grid 3 (pin 8) is connected to cathode.The 6E6P-DR (also 6E6P-E) a...

Hi Romy,Thanks a lot for your reply! Very helpful but there is some misunderstanding...I personally have a WE91A 300b Clone, no ambition to build something with the tb3-2000....There is a guy building one though... ( I would if i could!)My problem i...

I you have
an active speaker and want like to use Melquiades then you need a DSET
configuration, Find out where and how your Gryphon rolls off MF and
introduce the same filter from your DSET in the amp. Use much lower
value of coupling ca...

I am taking about coupling capacitor between driver tube and the DHT. There are zillion way to do it and no one said that they need to be used. No one proved yet that a very good quality of caps shell be worse than other methods. In my case since the...

[quote user="from email"] …. I have the valves etc. for the Melquiades but have not built it yet. I have begun thinking about the preamplification stage. Right now it is just purely passive. Is this not the optimal input for the Melquiades? [/quote] ...
