I understand that you needed to mirror this to suit your chassis, but I gotta tell you this hurts my brain. I turned your image on it's side so I can visualize it better, and also flipped a nice layout diagram from Rob's site. It looks like you may need to remove a ground connection between 2 of the big filter caps. Also, I think you need the ground bus (now across the top left), but maybe you're going to add the ground connections later? I can't really see some of the resistors there, so I'm not sure about the rest of your layout. I think you're now the expert on this particular configuration, so walk through it carefully and make sure you have everything covered.
