One nice feature of the Futurlec board is the diode bridge on the input. Now, why can't more manufacturers do this? I couldn't figure it out at first; then, "duh!", it hit me, it's reverse-polarity proof. Since the N-connector fits the Coridium board too, and there's no bridge, I hooked it center-positive for use with both boards. I originally had it center-negative because the Futurlec board was silkscreened with that instruction.
