Interesting you should note that as I've seen 10R and 2R7 (as per TI datasheet) in this location with a 100nF to make up the zobel. Have no idea if it makes much of a difference as all I've built used 2R7 but the last built module I received has 10R.

I have not built the amp yet but I am wondering if the
layout of my board is good and if I should get another PCB...

When you look at my photograph from page 1,


Click the image to open in full size.

Arenīt the inductors of the Thiele Network too close to the inputs (the white connectors in the middle) - and the feedback-resistors (I guess some of the little blue ones) too far away from the LM4780?
All the best,
Salar

EDIT: The Image might be squeezed, just click on it to see it in the correct aspect Ratio.
