[QUOTE="Llew, post: 668757, member: 175007"] It might be worth checking the current limiting thermistor next to the fuse. This prevents current kickback from the smoothing electrolytics when the power is initially applied, and can blow the fuse. When cold, the thermistor presents a (relatively) high resistance at the input to the power supply.if the resistance is too low at switch-on, the fuse will blow. Not sure ATM what it should be when cold, I'll look it up later. [/QUOTE]
