My work! LM4766 Full balanced

[bbp]

To build a stereo amp, I plan to use 8*LM4766!
I just finished PCB project with Protel DXP
Each board uses power regulator build with 5-10 mA current source and LM431 (adjust it to 32V)

Here is some PICs about it ,but I have not make real PCB out yet

my english is so so so poor

Make this PCB out, and ...

here is the bottom side

I haven't seen any signs of this yet Your english is quite alright.

Are you really usre about the parallel connection? Don't you need any resistors in series as the rest of the world does?

The post#1 shows the real schematic ,and post#3 only shows the theory,not the one I really want to build


On the PCB, I will use 4 * 0.47-1 omega resistors on each board.

here are both the side of PCB

Have you really tested to connect the inputs of LM1876 they way you do?

I really suggest you take a look at AN-1192!

Many thanks for your suggestion,actually I have not test it before,I made the schemartic through my experience,but I will test the circuit later,and then make a report .
