Hi all - I have a QJE PS60SWIII power supply which has been working fine for quite some time. It gives ne no noise on HF, but it has developed a small fault. The supply works fine but the AMPS OUT no longer shows on the analogue meter - VOLTS OUT shows fine. If I flick the V/A switch a few times then the AMPS OUT will show on the meter but the reading is well down to what is being drawn from the supply and after a minute it goes back to showing no amps on the meter. I haven't opened it up as yet as I was trying to fine a schematic first. Any ideas or suggestions ? Thanks Rob VK4ALL
