This clever little device went bang shortly after I bought it. The manufacturer was really helpful and sent me a bag of parts so that I could fix it myself. One of the MOSFETs had gone short circuit and blown the little 5 amp fuse, but also taken out one winding of the choke. I replaced all the bits and also added another fuse. This 1.6 amp fuse is fine for 300W at 240 volts and should protect the choke if another semiconductor should fail. I also put little stick on rubber feet between each diode/mosfet and the metal battens that hold them against the heatsink. This results in much more even pressure on each device and allows them to sit completely flat against the heatsink.
