don't build the schematic of Fig1.
It omits all the "national optional" components.

read the National Datasheet.
It mentions all the optional components.

But why I need them while I need to make a simply high power amplifier out of LM3886?

You really mean reading the datsheet for those components or read the application note?

Ok, I will take a look at those components in the datasheet. Thanks for recommendation, to see if I need them.
Any other idea please?

Thanks Tajzmaj.

Actually I want a one layer PCB with good and trustable traces, That's why I asked my request here so that other friends help me out with a good one....

You don't seem to know much about the details, so why not just cut to the quick and buy this - it's ready-to-go:
