Re: Defective/ fake LM317T
The aim of mounting the pot the way I did was to make it panel mountable and make the entire unit fit in a case. I would not have been able to do that with the supplied blue pot with a tiny screw for voltage adjustment. In relation to the wiring of the pot, the PCB already came with a tracing linking the wiper to one end of the track.
I selected a 22K panel mountable pot because I have no more 10K ones, at least for now. I also suspect my 10K pot may have been burnt by the IC, because it was reading in the megaohm range when I tested it after desoldering.
