Ok, so here it is. Scematic closely (if not identically) corresponds to carlosfm's unregulated psu with snubbers.
Any comments? :D |

And here's the amp itself.
LM3886, modified RoadKill's pcb.
And yes, I know, I shoud've used polypropilene caps wherever possible but they are very hard to get here and are a bit too pricey. I just hope my amp won't oscillate :) |

the layout looks good for me,what is the footprint size of C3 and C4?
It would be better if the corner is a little softer. |

Diameter 35mm.

| I mean, that PCB of PA is uncorrect - pin 1 on output must be grouded. |

Upupa: no. That's a feature of RoadKill's design, it has been debated and seems to be good thing. After all, I can always connect these tracks or even ommit zobel...
digi01: thank you, the corrections make sense. :smash: |

No more faults spotted?
Good, I'm off to make some PCBs then :) |
