Really interesting findings Jerry, I know your not into DIY as such but would you be willing to solder a copper bar in place where the fancy fuse is? I understand Garry not wanting to do this for fear of trashing his equipment, but as your new fuse is only in a wall plug which isn't actually directly attached to your equipment there is no risk as such? I would do it myself but I don't have any fuses in my mains .
