Cosmichorus production PCBs are in and perfect!

This is the biggest, scariest part of the whole Cosmichorus project... the production PCBs! These are basically what it's all about, made for us by Creative Circuits Inc. in Ontario. I've built two and they're perfect, huge relief, huge progress, next stop finished enclosures!
So here's what they look like when I take one out of its anti-static house:
Loverly purple with all the smd components installed by cool robots. The audio op amps are ST Micro LM833, the companders are CoolAudio V571, Texas Instruments TL062 for the oscillator, National 13700 for the Hold. All resistors are Panasonic 1% metal film 1/4 watt, all the caps are Kemet 5% multi-layer ceramics 50V NP0.
Here's the stuff I add to the board to get it ready to build:
Neutrik jacks, Panasonic caps, Copal trimmers, Fairchild 5088s, hand-rolled opt-coupler for Rate, Panasonic MN3007 BBDs and MN3101 clock, ATTiny micro for bypass with Panasonic relays
Here's what it looks like after that step:
Here's the rest of the parts that go into the build:
Alpha dual gang pots, Alpha single gang pot, Alpha clear shaft pot, Davies knobs, R13-85A stomper, Mode power jack, Carling toggles, 3mm and 10mm LEDs, and a big metal eyelet and wire for grounding the box.
Here's what the board looks like all built up:
And here's what the two production pedals will look like except for their finishes... two nude production pcb/proto box Cosmichori with the LEDs and knobs they'll have in the production versions:
Next update will be finished enclosures... couple/few weeks!
