PCB1 Blown (again)

Last weekend my PCB1 blew another channel (the second time this has happened with no apparent cause.) So I have removed it and will replace it with a single-channel Vantec (which I just ordered) for the dome rotation control. I am also building my own power supply board with 2 variable voltage supplies plus 5V and 12V regulators. I have put PCB1 and PCB2 up for sale in the builders group. No need for PCB2 now that I am using the Mac mini and the Phidgets boards.
