Default Aleph P 1.7 pcb

I have to do a final netlist check, but all comments are welcome.

I'm thinking of reserving more room for in and output coupling caps.

And has anybody made an Aleph X P 1.7?

No, I used Ultiboard 2001. When the board was almost finished I got sosick of UB I started to search for a replacement and found protel dxp. Unfortunatly layouts are not exchangeble for as far as I know. And finished it in UB.

What are the dimentions of such caps?

10uF might be quite big.it might be 15-20mm thick and 40-50mm long,but at worst case.

Default update

I finished the new lay-out.

The couple caps are now 25mm x 40mm. To save space, all the small stuff has to be placed on the other side then the couple caps.

The TO-92 devices have now a slightly different package.

And it fits on a standard 160mm x 100mm pcb.

The components have the same numbering as the Aleph P 1.7 Service manual.


And a final question: What would better for the gain pot? A normal pot or just a simple adjust pot.
