I am trying to get a PCB board made following the schematic for the 200W Bridge-Parallel specified in:
http://www.national.com/an/AN/AN-1192.pdf
with 6 x LM3875 per channel instead of 4 as in the App Note. Before I send it I was hoping someone would point out any errors...
The ExpressPCB file is attached.

Thanks for replying.
mwmkravchenko: good point on the thickness of the traces. thank you. I started with a servo version but it became too complex and I too lazy to finish it....
UrSv, nice work much cleaner than mine... Would you mind sending me your version? BTW, I didn't read the whole thread, did you end up making and building the PCB version?

I built mine ptp... then drew the schematic i used w/ expresssch and then built it in expresspcb. I have not tried the pcb yet... i haven't had time to refine it, although i'm almost positive it'll work. is it all it can be? i doubt it, this was my first attempt at a pcb layout, never done one before... send me an email if you want it
