With all advantages of DSET with multi-ways it is a pain in ass to maintain it. For instance now I am chasing for 2-3 weeks a mean thing. Whoever use 6C33C know how the tube dies – it begin to produces from time to time those dry non- harmonic bursts...

Thank you, Romy. I suppose to the notion of generic optimization is an oxymoron: like talking about an off-the-peg bespoke suit. It is either Savile Row or it isn't.What would be desirable, however, is not to have to do it all oneself: where do...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.

I already have some PY500 (it's a sign =))) ) and I have 836 too.I read about Malquiade amplifier threads.So it seem peoples on this forum like horn speakers (I love them too) and are looking for fast transient response, it's exactly what I like.But ...

For whatever stupid reasons the DSETs (Dedicated Single Ended Amplifier) are not as popular among audio people as they SHOULD be and this imperfection I am trying to attack.
So, if you use SET for whoever propose then it fine but if you e...

[quote user="Merlin"]... my own feeling is that David Berning's solution is both neater and more practical - the only impediment ot it's acceptance, the dogmatic approach of many thermionic die hards. My experience suggests it's their loss. [/quote] ...

[quote user="Romy the Cat"]I am sorry; I do not follow what you are saing. I see no relation between a need to use a crossover with DSET topology. The Cat[/quote]What I am thinking is that with full range amplifier, you must use a speaker level cross...

Still partially wrapt in mystery, but here is potentially the first SS DSET:http://www.firstwatt.com/sit1.htmlI say potentially for that is not naturally Pass's direction, but each monobloc is designed to be tunable to its specific speaker....

Stitch, even though you are not wrong what you say but I do
not think it has a direct relation to what I call the "worse". My angle
was different: the demise of SET concept if the amp increases some rational cost
level. The cost of LAMM electronic...

...seems to me finacio-emotional not technical. The Macondo and 9 channel Melquiades are really one device, essentially an active speaker. If a maker did not feel obliged to put the amp and the speaker in different boxes he would obviously optimise t...

Wow, I mean really, really, really, really, really WOW!
A week ago I converted one of the Super Milqs to 5:1 loading and yesterday I converted another one. I loved what the last week converted amp did. It was very nice but today I put the entire sys...

[quote user="drdna"] How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range. [/quote] Hm…....

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...

KOTriode, this is not the subject of this thread but I would like to point your attention to one aspect. From one side it looks like you with some kind of special pride talk about your Tango output transformers. From another side you are stupid enoug...

My DSET amplifiers are starting to go together (slowly).Bias string and bleeder relays/resistors...The remainder of the filter caps. The middle floor goes on and the filter cap for the First Stages (6E5P/6E6P).Then the OPT's go in place and the shel...

Hi Romy,What a busy year just gone! Finding enough time to just sit down and get the DSET's going has been impossible, but I have time now and have started the process.At the moment I am introducing some high voltage to the first amplifier chassis, ...

Hi Romy,I am designing the power supply chassis for the DSET at the moment and hope that you can remember some things about how you managed the grounding.All power supply components up to but not including the filter caps for each power supply will b...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

In this thread I would like to talk a bit about the practice in DSET driven multi-way horns configuration.

[quote user="Romy the Cat"]However, you need to find out how much power and how much gain you need for you subs and your room. Borrow for someone any 6C33C and measure how far the 6C33C will be from class A2 at a level of max tolerable bass in your r...

[quote user="rowuk"]I have experimented
with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that
ceramic drivers with SETs that I have heard being suboptimal, but after a year
of DSEP, at least for my use case, I am quite conten...

The Bass OPT's for my DSET have been wound. We have come back to a 1000R plate loading and into 1R the 6C33C grid clips at 9.36W and 5.8% distortion. The -0.5dB points at full power are 5.9Hz and 5kHz.A nice result really, and about where I thought...

To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply. There are quite a few differences to Romy's published schematics but it is basically the same beast. You will notice a lot of power transfor...

This is not as simple question as one might think. If a person embrace DSET topology, let for instance to take my example of 6-DSET channels, then what to do with cables that feed the DSETs? In my case I use one interconnect between preamp and DS...
