LampizatOr Amber II Fuse Location


I own the Lampizator Amber II DAC and wanting to change the fuse.  Lampizator owners do you know where it is located? There is a skinny slot where the pc connects but I believe it is a spare fuse holder but not sure.  Can’t see good anymore and that doesn't make it any easier.  Any help or pics would be greatly appreciated.
