fuse options for Aleph JZM

I just finished building the Aleph JZM and it's sounding great! Thanks to this community for helping me getting it up and running. I currently have a 10A fuse at the IEC as per the instructions. I notice that on the First Watt site, it says a 3A fuse can be used. I'm wondering if I can use a different value fuse from 3A to 10A without any issues?

thanks
 
Donut VA/Mains voltage

then take first closest value, down or up

use "T" or slow-blow fuse

example:

300VA Donut, mains Yank 120Vac

300VA/120Vac= T2A5

if having 2 Donuts - dual mono build, each Donut must have own fuse and - if possible - own soft start (NTC or more complex)
