what is pin 4 going to?
Pretty low power 1W amplifier. Not going to be very loud, maybe clock radio loud.
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
But learning is not learning anything. He is just annoying us with all his pcb designs.
We like to discuss electronic circuits on these electronics chat forums but you never discuss electronic circuits, you just show pcb wiring.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 !

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.

Now I have updated it !

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.
Just not sure what you intended.
There are more and more very young kids from India posting on these forums. They think we are teachers.
