From the vendor
Based on R.G. Keen's schematic, this board will provide approximately 18V, 25V, 33V, and -9V off of a single 9V source. Also, it has an option for a 9V sag, letting you dial in a value between 0 and 9V. Minor fix required. Add a 2k2 resistor from lug 3 of the +9V_SAG to ground. Only necessary if wishing to use the sag feature. Layout designed by delyk PCBs
