I bought the below variable voltage power supply from eBay last year. It worked fine when it arrived. I left it alone for a while and it seems to have stopped working,
The component with 330 printed on it appears to be overheating. Turning the potentiometers does not seem to affect the voltage or current output. The voltage is stuck at 0.4 and even when I short the output, I get 10 mA maximum.
Can anyone here interpret the fault?
