Almost there! Here's the SMT version on the bench, everything works as expected, just like the thru-hole version. That's obviously what I was planning, but sometimes things don't go as planned. I sky-wired the bypass caps onto this one, the "final" artwork has them added. I discovered that I just overlooked the bypass caps, they actually were on Dale's original prototype. One of the little problems of not having the full documentation and having to reverse engineer it from prototypes, occasionally things fall through the cracks. 
One task is to make one more pass through the prototype to make SURE nothing else was missed, though the buffer seems to function as well, or actually a bit better than the prototype. The astute among you will notice I socketed the AD744 chip, even though I probably didn't need to. This was to have the assembly house do that it of soldering of the socket to save me from having to do that as well.
I'll be sending the PCB and build info off to the assembly house for a quote on the boards, components, and assembly. Once that is in hand, we'll kick off the actual order process. I already have prepped a bunch of cases, but I will have to order more, as well as more power bricks.
It's been a long road, but I see the destination in the distance. 
After the PCB house gets done and I get the boards back, I have some discrete stuff to still solder on. The LED's are somewhat tricky as they have to be extended up to protrude from the top of the case, so spacing is critical. That being the case, I decided to solder a few parts myself after the automated build. Trying to space the LED's by hand was tedious and difficult, so I created this little fixture to aid in the process, it's used to place the four components indicated. The pins are alignment pins, they engage the mounting holes to precisely position the board in the fixture. The extra holes are just to clear the capacitors already on the board.
This is the board in place for the soldering of the four components. You can also see the two bypass caps I added. It didn't seem to miss them, but since they're probably a good design practice, why not include them while I can.
