Objet : Re: Alpeh X --
<<Hi, I'm currently working on a new A-X layout, based on Grey Rollins original schematics with a few modifications, I've chosen to use Zetex mosfets for the input difpair, added miller resistors and i'm probably also going to use Exicon Lateral Fets for the output. The Exicons are specially made for audio so i tought i'd give them a go. You can follow all this work on http://www.ruffneck.net
On my homepage i have also posted the gerber files for the first A-X i did. This one is based on the schematics of KK and with a gerberviewer you can find out the values of each component as they are printed on the design. You can also send the gerbers to pcb fabrication BUT i do not give any gurantees that the layout will work as i have not built this one myself. The only report i got in was that the ccs fet for the input pair fets need to be turned 180degrees. >>
Bon c'est un peu du Chinois pour moi, mais bon on doit s'y retrourver.
Idefixes confirme le choix des Zetex en entrée difpair.
Remarque : c'est son second AX.
Seconde partie :
Hi, i'll try to answer the best i can.
> Hi, Nice to read you, thank's a lot for the answer.
> I've bookmarked your site !
> But still some questions
> 1° - What is the power of your unit ?
The one i'm working on now is about 40-50W into 8 ohm
> 2° - Which values needs to be changed to obtain 50W ?
> 3° - Do you have a part list of the components ?
Those are printed on the schematic, but i will post a complete bill of materials once i'm ready.
> 4° - For the PCB do you think that the gerber's files are enough ?
For fabrication of pcb's, yes.
> 5° - What about the estimated cost of your Aleph without the box ?
Tough one to answer. i would say about 200-300EUR, depending on how much money you put into transformers and capacitors. I bought a nice set of 89000uF capacitors on ebay.
J'ai tenté d'extraire les data des fichiers Gerbers mais sans réel succès, XP...
