Eduardo, is it OK to post your original PDF here?

It's not so easy for someone who doesn't speak spanish to register at that forum.

I have no problems... But i think credit must be given where credit is due: Just make it clear from where the file came from. I owe nearly eternal gratitude to some of the members of that forum, for supporting my efforts in designing this last version of the amp, suggesting improvements and alternative components to the original conceptual schematic, and also actually trying those modifications!
And i also owe to people on this iorum, specially to Bruno Putzeys, who was the one behinf the UCD technology and inspired me to start designing class D amplifiers.
If all those conditions are met, then, yes, you can repost the PDF file

Cacho, Aldemarar, Tacatomon, Ejtagle...

It is a pleasure to see around here.

Is correct to draw an allusion to the real creator of the amplifier, "our" Ejtagle. (Eduardo Tagle).

The amplifier works. And does it very well.
All comments, and the history of this amplifier, can be viewed at:

Ampli HighEnd ClaseD UCD de 25W a 1250Wrms sólo con 2 mosfets N - Página 44 - Foros de Electrónica

In Spanish.

And the original scheme is the Annex. Not that Andrewlebon published in the first post.
Best regards and sorry for my bad English.

Hello Bushell,

I guess you didn't bother reading post #13 which contains the original document with PCB layout and parts list; not the truncated version you have attached.

Don't worry, Bushell, the ejtagle diyAudio member is the same ejtagle member of the Foros de Electrónica - Comunidad Internacional de Electrónicos forum. I susbscribed to diyAudio several years ago, but i have nearly no posts. if you use the search feature of diyaudio, you'll find the only post i did at that time, that was an UCD amplifier for an ESL loudspeaker. That was a conceptual schematic, but i never had enough time to build it... Maybe some day i'll do it, maybe never... (but i'm still interested on that subject... That combination has the potential to provide extremely low distorsion figures, and extremely high sound purity... So, definitively, it is on my pending-to-do list == And, to also prove that i'am the ejtagle of foros... here's the same message, but in spanish

Bushell: No te preocupes, soy yo!

Saludos al foro!

And also greetings to the diyaudio members!

PD: Please, don't start the 3rd world war by cause of this design!
