Here it is almost done.  There were too many wires going from the amplifier board to the power board, so I  reduced the number by daisy chaining power and ground cables.  Hopefully this doesn't affect the sound negatively.
I have made changes to this since this picture, but this will be the general layout.
Now I have to finish drill holes in the front panel for the headphone jack, power switch, and LED, and in the back, I need to cut out the rectangle for the IEC.
