The PCB company are on chinese new year at the moment i belive, so my order is still at there end. I asked if i could make a minor ajustment without effecting the lead time, and they said that was okay. So, i have changed the power supply to a more simple CRC type, and used diode arrays to save space and give a more tidy board. The BOM will be updated shortly. I reccomend using 22,000uf caps for C9 and C10 and somthing like 6,000uf caps for C11 and C12. The resistor bank is an option that you may wish to take, but i would reccomend this for stabilty. As you can see, the PSU has been re routed, i belive this to have a positive impact on the overall design.

You may find the new design here
