Another way to connect LM3886

I found this circuit and the grounding look very interesting.

An externally hosted image should be here but it was not working when we last tested it.

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.
