OK guys , hit a bit of a bump here. My power supply has been built and is done. First time I hook it up the voltmeter shows about 0.54V and the ammeter doesn't even move when I turn the dial on the 10k pot. I made some changes on Kris's design though . I couldn't find the 2 x 1Ω , 10W resistors in parallel , RE1 and RE2 , so I swapped them for 5 x 0.1Ω , 5W resistors in series. I added a voltmeter between CN1 and CN2 and an ammeter in series with CN1. Any ideas why nothing is happening? Did I do something wrong or is one of my parts defective? If so so any ideas on which part to replace maybe? See the final PCB layout attached.
