I did not state the fuse current rating is dependent on the voltage, only that you will need much higher amperage fuses (according to Georg Ohm) if you changed the wiring of a 240v amp to 120v.

This is incorrect! The current rating of a fuse is independent of the voltage. The fuse blows as a result of heat, which is proportional to I squared times R. The voltage rating is just a guarantee that if it does blow, it won’t stay conductive due to an arc.

Of course 250v fuses are also fine with 120v amp wiring but the amperage will double.
