Very impressed by Nelson Works.
Try to build Aleph3
Get some difficulties to find parts in french.
Try to creating a french community of Class-a Amps (Nelson Pass prefered)

Re: aleph 3 french newbie
What happens if you use IRF244, 250 ,150 OR 140.
They look very simular in the data sheets.
here in norway its more difficoult to find one electrnic supplyer that have all the parts you want for a projekt like this. for example can i use IRF 9510 insted of IRF9610?
Get my point. sorry for my bad english

It's best to use the IRFP240 it's appropiate echivalent to the original used by Passlabs!
The problem is with the other that you mention is the Fet's high input capacitance,this should cause some problems in the high frequency region (like distortion)!I know from my experient's!

Thanks
but i was planing to build an aleph 4 or 5 and a aleph P
and the aleph p uses a IRF 244. should i use a IRFP240 or an IRF610? . The Balanced bride of Zen uses IRF610 but then you nead a -60v supply to. any suggestion?
thanks

I observe that there is a lot of people interrested by Aleph project.
You can be conduct in the Solid state amp to view the Aleph P pcb that I dreaw, and the Aleph 3 project that is the biggest tread of this forum.

Oh yes ! ! I'm accepted in engineering school. In alternance I will work for Pirelli Cables.
Woh, Woh ! ! I'm so happy. Great thanks to the CESI.

My duty in Pirelli is to manage a little team of technician for the maintenancy of the production of the factory.
I make the continuous improvement of the production.
TWe product electric wire for little voltage (< 5000V) but for high charge. And more specificly wires made to be bury.

Here's what NP says about output transisitors:
The IRF244 is pretty much an IRF240. We
use it instead of the 240 because it has
standard TO-3 pin width, where the 240 in
a "to-3" case is nonstandard.
The to-3's are very difficult to get, but the
IRFP240 plastics work just fine.
I found it in this thread if you want to read it all..
