I recently put together a Castle Multi Gate, and I am having an issue of not receiving a signal out of the XNOR output. I will include a photo of the pcb. I checked the points with a multimeter and seem to be getting a normal connection. I receive normal output gates out of the other 5 outputs, just the XNOR I am receiving nothing. Thanks
The problem is somewhere in this XNOR region, as the XOR is working fine. im thinking maybe a faulty resistor? as U3 and U6 are working for the XOR.
