Find out the pinout for your aphex box's edge connector, buy a 30 Pin Card Edge Connector and a 51x Card Edge Proto PCB Adapter from Classic Audio Products of Illinois. Then all you need to do is "connect the dots" between the api pinout that Mark gave you and the aphex pinout so that your ins, outs, power, and grounds all get to where they need to be. Does your Aphex box have 48V? If not, that might be something you'll want to consider adding.
