The posted ebay supply has the same standard positive and negative rail design as given by the schematic in the previous post. Just change the elna filter capacitors to about 50V ones if you are using higher voltage otherwise they can explode!
I am in making of custom PCB for this. This will be for the preamp we are designing in other thread to include +15, 0, -15 and +24,0 volts regulated supply for PASS B1, CNC phono and LDR volume control.
