I got myself another dAD7 which is in working condition (apart from some minor fire damage). Bizarrely, one of the capacitors, C236, has the 'polarity' changed (legs crossed). Compared to the PCB layout and schematics the polarity is reversed. Perhaps there has been a revision, however, it wasn't the case in the other dAD7. As the capacitor is the same as used in the factory, I take it was done there and an original change to the schematic.
