Steve, you shouldn't need a schematic. Look for a resistor between the output + line and the pot that adjusts the voltage. Determine the value and add a shunt resistor across it that is maybe 10x the value determined. See if that drops it down enough. Adjust the shunt up or down to get the range you want. Also note that if this is a linear supply setting it for a lower output voltage range will increase dissipation at full load and possibly require better / forced air cooling.
