A great Brazilian Audio Designer that vanished from the internet .... He was at Geocities for long years, and had instructions how to design an amplifier, then, suddenly (2009) vanished.
People said the reason why he vainshed was because he found too many people copying and selling his stuff.... this is something that really bother us a lot.
Now a days he has a site and sell high end equipments...no more schematics, no more lessons, no more kits.
Here you can see one of his amplifiers...if you want to analise it i gonna be happy to listen your thoughts about...was hard to find this schematic, it likes he removed everything from the WEB.
Here you can see his site:
http://www.timiaudio.com.br/fmt/sca9900.htm
Sad stuff...this guy helped a lot brazilians....we had no knowledge and he was a breath of fresh air in our lives...hurts me a lot to know he give up to teach us audio electronics.... well...i can understand that, but i cannot accept because Brazil is so poor in such kind of knowledge...so poor that i am one of the famous ones and my knowledge is so small compared to Fabio Timi.

Carlos

My effort not to lost this one too...as everything was deleted
Sad stuff.
I have some comments, in portuguese, about this amplifier (schematic show in previous post) but i could not upload it (docx 145K)

Carlos,
I can see why he deleted it!
This shows a keen, insightful mind. He is a very clever guy, and the amp you showed us, although complex and high parts count, would sound very, very good. Extremely low phase shift....... and wonderful spatial characteristics, no?
Ciao,
Hugh

I really do not know dear Hugh
I have not assembled. In the past i found it overcomplicated, but this kind of analisis you made is what interest me.
Thank you,

I love the idea of "mirroring" the bias spreader, separating it from the pre-drivers' bases 
And yes, clever ips/vas combination, light compensation - low phase shift. Nice.

Not everything. Here are some more information on this amplifier:
AUDIO espresso - editorial
Some information from the old webpage can also be found here:

I have never listened to it, but it seems quality may be good
Despite he worked with 0.1% THD and now a days we go 100 times less...also he used to make some overcomplicated circuits.
Well, considering that speakers distorts a lot, there's no point to search for low levels of distortion unless you use special headphones or special speakers...so...the now a days advantage in distortion may not appear in real life audio reproduction..... well...... we try our best with the speakers we have now a days.
But i do think it is a pitty he is out from the Community as he is a high level star in my country.... we are very poor in knowledge about audio in Brazil...several factories used to copy schematics...most of them use Marshall Leach variations....very few guys are dedicated to audio..... so, when one is out, a high percent is lost.

Hi Carlos ! Do you mind sending to my email the comments in portuguese about that amplifier ? My email is silvino_ramos@hotmail.com
Thanks
Um abraço de portugal
Hello Carlos,
Could you please send me over a copy as well (brzappanale@gmail.com)?
Thanks in advance.

Down the publisher's page is written
"this amplifier was entirely developed with the help of a computer, it was not tested real life"
So, this is what they said down 90s
It is a word docx and i could not attach in our forum, despite the size is fine within the limits.
Down this page, at the signature line, one example about what many Brazilians have inside their hearts.....humanity

Hello, Carlos.
Do you have more schematics designed by Fabio Timi? I remember his website (Could Not ConnectCapeCanaveral/9096/projetos.htm) which is offline. Could you please send me any projects of him you have?
Thank you in advance.
