fast vs slow blow?

[Mizno]

on an old pre univox (unicord stage 25) amp that i have i blew a fuse and it says to replace with a mdv 1/2 amp 250v fuse. would i have to use a fast or slow blow fuse for this? im not sure and i figured i would ask around before i went and got some

most amps need slow-blow fuses due to inrush current when first turning them on. You want the fuse to be able tolerate the elevated inrush current while the filter caps charge up but blow if there is a sustained over current situation such as a short.
