When you replace, with a stable solid directional device, a magnet the increase in performance is incredible.
A magnet has directionality built in and can follow the signal path in a circuit providing another enhancement. Tom
All your answers prove you are delusional about ac mains fuses, especially them being "directional" in an ac mains flow, that "changes it’s direction" 60 x a second (60hz in the US and 50hz in Au) THAT"S WHY IT"S CALLED ALTERNATING CURRENT!!
You would have to pull the fuse in and out at the same rate (60 x a second) and not breaking ac <> flow to hear if were directional, that’s just how delusional you are.
