Does this work or is this a myth?
It's a myth, a 50c fuse sold for $150 is a con aimed at the gullible.
Just change the fuse if old for a quality brand EE industry standard 50c fuse, as fuses (even the snake oil ones) do age after many turn on cycle surges.
Quick blow fuses and slow blow fuses aging left to right.
