Hey Bill! Each stth6002c "diode" is actually 2 diodes inside.

There are 3 legs. One diode goes from Leg 3 to leg 2, and another diode goes from leg 1 to leg 2. So, each stth6002c part can handle 60amps RMS. So, 10 can handle 600 amps RMS. Isn't that sort of confusing?! man! Diode Makers these days!

Watt: The control board is all labeled with each part number and orientation, so it's not TOOOOOO bad, but still. hehe.. Definitely a place where a lot of mistakes could creep in. That's why I would really like to remove the human from the loop on that part. The rest is basically like putting a puzzle together.
