Greetings All, I bought the 3 ch mixer/splitter board and built it however I have a few issues. I don't know if you could help. First it appears the PCB board I have is a different layout to the photos I have seen by others. I have the version that the documentation says revised 11-25-23. I had to inquire w PPCB because I had to get a schematic. I know they had changed polarity symbols for some components. So everything went well however when I went to power and test it I had no LED light and no signal passing through. I assume it takes a 9VDC power. I am using a pedal power brick. My first problem was that I thought R100 was a 10K and actually a 10ohm. I changed that and still nothing. I tested the entire PCB from point to point between pads to component legs and I have continuity so it doesn't appear to a PCB damaged board or trace. The PS capacitors are all installed correctly polarity wise. It would have to be a problem with the group of components near that section of the PCB since everything else is per channel. I suppose I will have to desolder them one by one to test their value and see if they are good or not. Thoughts? Thanks in advance!
