You must first check if there is a short in your power supply. Replace the resistor of the same type (225 k) as before and remove the fuse. Then solder a holder to the location where the fuse was. Then put a 100w filement light on that holder and power it on. Then tell me if the filement light is on continuously or not. I will tell you second what to do next.
