Aah yes, thx for the Eagle .pcb file.
As I can't find any component values or part designators matching the P 1.7 service manual, I think you don't have a corresponding schematic file. You perhaps did the artwork directly without drawing a schematic first?

Hello Thomas

The Aleph P sounds just really wonderful. Basses are really tight and firm,
voices are clear and natural.
The picture remains calm and very pleasant to listen to.

And better than my Hafler IRIS NAIM32.5 and GAS THOEBE


I would like to thank Nelson Pass and everyone else attached
to Pass Labs for everything they have done for the DIY community.


Nick

Default Sorry for reviving, but schematic is in error

Dear Nick and others,
Thanks for the very nice layout, but i feel that there are some critical errors on the final pcb (more on the files in pcb.zip). On the final pcb the orientation of the rightside ZTX are in error (E$66 and E$17); they should be facing the same way as the leftside. Now collector and emitter are reversed on the rightside (with devastating results). Also there are two 221R resistors that should be 221k (E&39 and E$42). Also on the pcb.zip file there is a trace error from the 80v reg input; it runs to earth instead of the correct resisitor. This is corrected in the final pcb.
Can anyone confirm my suspicions?
Thanks!

Regards.
