360 Systems Midi Bass Fuse

Does anyone know what size fuse I need for a 360 Systems Midi Bass? I found it after many years of looking in my storage, but it’s missing the fuse.

I’ve read on another forum its a 1 amp fuse but my manual says its a 1/2 amp

… .I’ve just started today looking through 40 years of gear to try to find my fuse assembly (I found my MIDI bass thought) LOL
