I just measured the voltages, I see + 30.5 volts on the 30V line, 0 volts on the 18.8 line. This leads me to assume that something is amiss on the A-15 regulator board. Looking at A-15 outputs on the pcb edge connector: Pin 4=0 v, pin 12=30.5v, pin 18=9.9 v, pin 15=0v. These readings may make more sense when you have the schematic in front of you Again, thanks so much, let me know where else to look.
