Default Questions on Brian's PCB PS (rev3.0) ??

1). In the schematic the the C1 (0.1) of RC network connect to ground, however on the PCB the R1(1Ohm) does instead. I wonder if the RC placement on PS PCB is also correct ( i.e. the order or RC or CR doesn't matter) ??



2). About the R5 that series with the LED, what is the proper value (+v,G) in case I use the 24Vdc and 35Vdc, respectively? Will the 22K 0.5W and 47K 0.5 work?

Thanks,
