You can also get some values of 250v ceramic fuses at Home Depot, etc. 
They are used in microwave ovens. I agree that slow blows are not likely 
to be correct for an amplifier -- they are very slow and are often 
specified for motors, etc. If an amp needs a SB it probably needs a 
soft-start. You would want a fast blow in case of an arc or something.

##  yes, make sure you use 250 V rated fuses... even though each individual fuse
is in it's respective 120 v hot leg.  Reason is, if ONE fuse blew open, and the other
fuse remained intact, draw it out on paper, and you will see that you have 240 vac
sitting across the open fuse.   Only use 125 v rated fuses  in  a  120 vac circuit, IE:
hot and neutral.
