slow blow or fast acting fuse

Hi I was hoping someone can help me, I have a
sony str-gx69es receiver and I wanted to upgrade
the fuses.The fuses for the power supply are
125v 4a and 125v 8a. The other two are for the
speaker impedance selector which both are 125v 8a.
I would like to try some hi-fi tuning fuses but I
don't have a clue if they are fast acting or slow
blow. I appreciate your help. Thanks!

Why even waste the time trying expensive fuses that are unlikely to make much if any difference with such a receiver ?

It is not normally my practice to make generalizations, but a Sony receiver is not in the same class as a Fisher 500C. I have loads of restored vintage equipment, and a nice sounding old skool Marantz SR-19 AVR. Would I bother trying expensive HiFI tuning fuses in them ? No. IMO, the OP's money would be better spent having a tech give his Sony receiver a checkup. If bias or DC offset have drifted, adjusting them may prove more beneficial.
