Hi guys, I’m trying to build a power supply based on lm317. The skematic is posted below
I made this circuit recently but the output voltage is not the value I expected. It is suppose to be controlled by the 5kPot and 2.2k parrallel network. However when I turn the pot the voltage remains the same at the output, approximately 16v. (The same occurs unload or loaded).
Below is a photo of the solder trace, All connections were made according to the schematic.
How would an electrical engineer troubleshoot a circuit like this to make it work?
