(one more) ALEPH P 1.7 clone
2 Attachment(s)

With several people from Audiostereo forum we decided to build ALEPH P 1.7 clone.

I will use ERO 10uF caps for input and output. There is also place for BG N type 10uF and 47uF capacitors on the PCB. WM8816 chip will be responsible for volume control. I tried to locate power transistor in one line. Connected to one heatsink they will work in the same conditions.

Suggestions seen miles - this will be my first PASS LABS construction working in A class.

Mr. Pass thanks for sharing this project ;)

This is how PS board look. I don’t like GND track so there are few things to correct ;)

There are no pictures yet. This is just a project. I will order several of this boards so they should be ready in a couple of weeks. I can’t wait the results and sound of assembled preamplifier.

And here is a nice 3D view of Aleph P PCB.

Hello veteran,you have make a very nice layout.the only one problem for me is the input with the power supply distance too near.
have you get a chance to see my layout?

Looks nice. : O ) how much for a board >? How about that Volume control i have been working on with you ? the ladder one ? A display ?

Hi Digi01. Your pcb is really nice too :)
I tried to reach compromise between power and ground tracks. As You can see they are connected in single point. But small MKT cap close to transistor may be useful ;)

Jleaman, to who this question is? :)

I think that this may be the final look of my Aleph P 1.7 pcb:

There are few cosmetic changes and the PS board was modified. We are ordering couple of them and the cost of complete set (PS + 2 x Aleph P = stereo) will be less 10 Euro. As soon as I get them and assemble one I will put few pictures here :)
