Replacing fuse


Would replacing an 6.3A SLO BLO fuse with an 8 SLO BLO fuse be ok? Thanks for any information.

Yes the correct size is written inside of the amp.Searched online for audiophile fuses with the same value but was not able to find one.8A SLO BLO was the nearest available.

6.3A is a standard size and all the audiophile fuse manufacturers make this size -- Synergistic Research red/black/blue for example all available in that size

Bought the fuses from Parts Connection located in Canada on sale, which makes the sizes and values limited.Know there are correct size fuses but didn't want to spend $50 or more for one fuse.Its a Hi Fi tuning fuse which many have for sale but none have the size and values needed.
No. The design engineer knows the expected fault current and from there determines how much time to melt the fuse, and that corresponds to 6.3 amps for your device.
