Just finished assembling my LPU in preparation for firing up the boards set I purchased from John. Everything looks good, expect for the -12v supply. I have a Janus board I'd like to try, so I can't just disable this with the jumper. Voltages on LT1931 1:11.78, 2:12.19, 3:5, 4:13.6, 5:13.65. I expected to see a -12v on pin 1, but see +12 instead. V at pin 12 of J1 is 65mv. Checked polarity of C20 and D1. Any ideas would be appreciated.<div>
