Not sure on vacation America but typically a manual will specify slow blow , if not specified it is a fast blow . Always replace with proper amperage.

I looked at the schematic and it’s not noted on there either. I’d be comfortable using a correctly rated fast blo and asking CGC if the slo-blo mentioned in the note is the only one since the schematic makes no mention of it.
LTG probably knows.

I would say they are slo blo. Fast fuses are very seldom used in pinballs.

Lamps take a power surge when turned on cold, so a fast fuse may blow too easily. Solenoids use way more current than fuse rating, but since they only pull in momentarily, slo blo fuse stays intact but will blow in a few seconds if coil locks on.

Assume fast blo if the manual does not state slo-blo. R3 and R10 are discolored, which means they have been taking on some extra current that they should not be.

What is the issue you are having with the game?
