Hi,
I need help using trafo. I use trafo 1 A, 18 V. After I unplug the cable from 220 V AC, there is still DC voltage output from the rectifier section. I must short circuit the capacitor to empty the capactior. Do you know why? It is very dangerous, I guess, you know the result when you short circuit 18 V DC, the spark. I use 1000uF 25V capacitor and diode bridge. How to fix it? What part should I substitute?
