Hi,
I've bought a couple of AMP32's from 41hz.com
The first ones I built worked immediately (know the instruction manual thoroughly now...).
On the last one I accidentally shorted two of the schottky diodes (positive VDD to ground 😱 🙁 ). It happened when I but bolts through the two holes besides the chip the nuts made contact. Nothing visibly burned, no smoke or funny smell.
I allready replaced the chip and N channel FET, still no led burns, no sound...
All legs that need VDDand ground are connected to the chip (measured it from the supply input wires till the chip legs).
Any help highly appreciated...

Oh yes and here's the datasheet (with schematic) of the evaluation board (claimed by certain people to be quite similar)..

Some help would be appreciated a lot...
