About the ono :
I have an untested layout by Edward Robinson and i want to indicate that it will need to be tested and fixed before making boards

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.

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.

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 🙂

fanta,
I'd like to go for thick copper - 170 mikro. Can guys from Lodz reach (or beat) this spec ?
P.S I am also based in W-wa, beer ?

It's polish thread 🙂
I'll ask tommorow for more cooper, but he said it can be only made with an additional chemical process. I guess it will cost more. Standard thickness amounts to 80 um.
Why 170 um? Kristjan use only 50 um.
