Hi everyone:
I've received so much help from you all on my Chipamp project, that I thought I'd make an (albeit small) contribution back. Here is a pic. of the Chipamp.com PSU with part numbers on top, as well as the LED power light indicator circuit and parts. Hope this helps someone. |

As has been pointed out in the past, the polarity of C6 is shown the wrong way round.

Actually, confusingly, it's the lower bridge that is reversed

I'm a total newbie with nearly zero electronics knowledge. If you would please clarify what you mean by that, I will try to fix the diagram. Last edited by Hogwild; 23rd October 2017 at 10:41 PM. |

Sorry, not clear. What do you mean by reverse? Do you mean swap label D3 with D8 and swap D7 with D4 or something completely different? |

Look at the two halves of the PSU - the same connections that give positive output on top give a negative output on the bottom
![]() Leave C6 and the other components as they are, but connect the D3/D7-node to the negative side of C6 and the D4/D8-node to the positive side. /U.

I can't really imagine in my mind exactly how that would look. Maybe someone else can change the diagram and re-post? |

Current only flows in one direction through a diode. Some of the diodes are drawn the wrong way and need to be reversed. This schematic keeps popping up with the same response.

The problem is only with the circuit diagram. The Chipamp power supply PCB is correct.
