The circuit which we are going to make is.

Thanks to cld000 for schematic drawing.

How are we supposed to turn that schematic to PCB?I am a beginer and cannot make much out of this schematic.I haven't the slightest idea how to turn schematics to pcb.Maybe you could enlighten us.

frens san ny one tell abt dat 0.01mf and 0.047 wch z the positv terminal in dat..... and frens......wat abt LM386 ic pin numbr 7.... y it z left blank.... no connction itslf or wat??
those caps don't have a polarity

um can i remove the 0.047? i got everything but that and i cant find it. Also how loud will this amp make 4 speakers play? with and without the 0.047
you can remove it but the sound quality will be pretty bad

can the 9v be a 5v???

Nope. It has to be a 9v, you can easily get the 9V battery.

Oh yes in the end I found a picture through which I can continue making my Circuit the graphical diagrams sucks....

hi i confused on variable resistor part :S
(removed by author or community request)
the negative of your 9v battery (-9V)
one more question... well i got a HWCAT CSC386P... will it work???

ok i am really confused... have you just made up your own symbols, have you ever seen a circuit diagram before? dont get me wrong this is a great guide but it would be a lot more helpful if all the symbols were actually real symbals

They aren't circuit symbols, they are what the components look like, arranged in such a way so that we can see how they are connected. It is meant to look like how it would on a Printed Circuit Board :)
This is a step where the yellow box things you can do would really come in handy. (hint..hint..)
