Can a fuse be the source of hum in an amplifier?

Not unless it's something unusual, in fact weird might be more like it.

Probably not. You probably live in an older house since you have fuses rather than a more modern service panel with circuit breakers. And most importantly fuse box electrical usually isn't double grounded which can produce ground loops. If you have a three pronged plugin its likely the round side of the plugin hasn't been grounded. You can add a ground if the wires are there. Lots of DIY'ers that rewire a house simply cut the second ground at the junction & wall box. You might be able to connect the second ground if its there at the plugin box. I did this with my house prior to moving in. Whoever rewired the house and added the 250A service box installed 12/3 wire throughout but didn't bother to install the ground wires since they left the old 2 prong plugins in the walls. They did leave the third ground in the wall curled around the insulation. I removed all those two prong plugins and put 3 prong versions and connected the ground wires at the plugins and the service panel. I got no hums!

No, you most likely have a grounding issue of some sort.
