Easier look at the sch. :

 

[DCPreamp]

Your PCB is lacking the op-amp and pre-drive circuitry. Where does it go, or is this sort of a "universal" power amp output stage? Still, very cool and nice effort.

The other side

 

[Federmann]

The board is double sided. Much of SMD components.

 

[Lee Knatta]

You have silkscreen printed over your pads.
Doesn't your board house remove silkscreen over pads on CAM import?

 

[Federmann]

For now, no foil, solder paste dispensing quantities automatically.

 

[Lee Knatta]

Sorry, I don't understand.

The PCB is double-sided, through-, two-sided solder mask, two-sided printing, gold, all Photographic method produces. Size is milled.

Soon there will be more pictures of the production.
