Aleph P 1.7 pcb

Wes Marquenie · 12th July 2003, 02:53 PM

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?

Yes,it might be hard to fit some audiophile quality polypropylene caps.Did you use Protel for this one?

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.

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.
