Hi to all. I need your help, because I've done lot of searching and haven't found any answer. I'm planning to build a chip amp TDAR based on this schematic see attached. But I have problems with designing PCB layout. There are many PCBs on the net, but almost all of them are for mono or bridged mode. I need PCB for 2 channell mode stereo. I have found a kit, that looks like this. Any help will be much appreciated.

Are there any fatal "grammar" mistakes in this PCB? Can I use this layout? Attached Images tda stereo PCB.
