Default Help with Aleph 1.7 PCBs !

I want to build me Aleph 1.7, and i decide to make some PCBs @ oshpark! i Modified a bit VETERANS PCB to accept WIMA MKS caps and second version to accept MUDORF MKP or EVO caps !

Here is Schematics i use to make PCBs:

I go to Mouser i read WIMA MKS datasheet, and make PCB f0r that particular capacitors:

... as you can see, i moved ground traces on the top layer of PCB and some minor changes!

This is how PCB come out on OSHPARK:

NOW, i would like to use Mundorf film caps for this preamp,

I am about to design PSU, and i am thinking to pit PSU on same board with preamplifier, like dual mono preamplifier, and also to make switch on board for BALANCED XLT to UNBALANCED RCA output !

Please let me know if i make some mistakes and what are suggestions for onboard PSU and output switch !

Thanx !

I assume you gents know that we have a group buy going on right now for AlephP pcb, for the original Wima caps though, (which do not fit on Veteran's board).

Aleph P is back!! (limited time offer)
