Another way to connect LM3886

[jamal]

I found this circuit and the grounding look very interesting.

Mixed AC and DC coupling.
Variable output offset.
Complex NFB.
Ambiguity in where decoupling is placed.
Pin 7 garbage fed to Signal Ground.
No RF filter.
No output Zobel.

Whoever drew this is either very clever or very stupid.

I would not risk copying it.
