Ack, Jamie. But look at

upper right corner this is IMHO not more than just a plain wire. You
agree?


IMO not a fuse, a jumper.


Well, if you look at the upper left corner on the frontside of the PCB
youŽll see nothing that looks any similar to a jumper:

drilled small holes. But anyway, there is nothing which could have
protected the circuitry of the PCB on the (N)eutral side of power
supply (230V AC). Nice manufacturer, I know...
