Thanks for your help Promitheus,

I have a little modified bls boards here
i have added a second pair of 1000uf caps in the psu file is avialable here :
http://www.polymorphic.org/~snail/bls/

Considering aleph boards i didnt stated it to cleraly yesterday
i need to choose wich layout will be most universal for this buy - i expect that not everyone wants aleph 5 like me

i have Mark's Layout
and it is really well done but for this bulk buy - BrianGT's layout will be proably better

cos it is more universal - but i only have a driver board and dont have any fet boards in pdf or gerber - only in gif
so if you know where i can find them
that would be great help


so to clarify things:
anyone who wants to participate in this group buy can propose aleph layout and then we will chose one wich suits all of us

how about boards for Aleph P that I am interested in - any broader interest ?

I have costed out boards for power mosfet's. I have the dsign now in PDF and HPGL format and ultimately it should be also available as gerber files.

Default PCB production

Hello ALEHP fans,

Maybe you should consider producing the boards in Bulgaria.
Take a look at : http://www.olimex.com
They produce high quality boards at attractive prices.

Regards
Piersma

Malisz,
If you can mailme this design it would be great

Considering the boards
it slowly becomes clear that for bls /aleph
we will use one sided / without metalized holes / with solder mask / Cu 170um


about aleph: p is it really sonically superior than bls?

did i mention that i want to make 2psu boards for every bls

Hi
Look this
The http://www.elpinpcb.com.pl they have nice proces.

If we make 10-30 one side pcb (aleph +2 psu, bls + 2psu - ca. 10dm2) it should cost ca. 2-2,5$ / 1dm2. Holes and cuts are included.
Its possible to make it golded.

Regards
