THe outputs are measuring a tad bit funny. For isntance, Q217 (Posted picture, large output on the right in the middle of the heatsync) is easy to measure:
Q217
Leg1: -29.85vDC
Leg2: -30.67vDC
Leg3: -29.32vDC
-All negative
Q114 is on the other side, in the bottom left corner closest to the LEDs:
Leg1: -29.8vDC
