Hi I need help on my project, I need to build a PSU that has outputs of +- 24v to +-5v dc by specifically using a 24v,2A center tapped, 78XX and 79XX series voltage regulators and a KBPC604 square bridge rectifier and the rest is up to us I did the schematic diagram in Circuit Wizard and when I simulate it, it works.. but whenever I transfer it on the PCB the negative values does not show the needed output. What am I doing wrong? If anyone could show me a schematic diagram with the similar set-up, could you please provide me with it so I could use it as reference. Thanks!
