This PCB is designed according to the datasheet of the IC. It is done in Diptrace and it is my first try in Diptrace as it is autorouted. Tell me about my mistakes if you notice it !
Why do some of your caps have "U" numbers? The output from pin 3 should go to the left and the power should come out from the top. With the decup cap as close to the chip as posible. Andy

What do you mean ?
What is the purpose of this forum ?
If all of yours hate me, please ban me !
Audioguru, I requesting you personally, please be decent with me as I have done anything wrong in this forum !
If you personally don't like me why you are abusing me as I have done any thing wrong to you !

Audioguru,
Untill I have completed my PCB projects I will not discuss any electronics circuits as if anyone of this forum does not like to discuss about my PCB difficulties so I will leave this forum with immediate effect. Remember I will do it with your non-cooperation. If you kick me then another one is waiting to recieve me as you understand it very much !
The amp won't work. Ground (Gr) isn't routed. I forget what I did in Diptrace to cause them to route. UNLESS this is a double sided board and all the grounds are vias?
A few other things are goofy too: Caps with U degignations. Overlapping footprints. Not using a connector for in/gnd and out/gnd or whatever. In/gnd needs to be close together because of the use of shielded cables.

Simple, all of the "Gr"s need to be connected together.
One way to do this is to use a 2 layer board where the bottom layer is a ground plane. Each Gr would be a plated through via to the ground. If you were making this board yourself, think of a wire soldered on both sides of the board, but you still need a few to connect your inputs and outputs.

Now I have updated it !

Can you tell me about 2 layers concept as I think that top layer is for component side of PCB and bottom layer is the copper side of PCB ? Am I right ?
