Counterpoint SA3.1 Power Supply question...what size fuse?

Picked up a used SA3.1 with the fuse door/fuse missing on the power supply unit. I’ve ordered the replacement Littlefuse cap but what size fuse is recommended for the 3.1 PSU?

Preamp was blowing the 2A fast blow fuse. Found this schematic wiring diagram for the Counterpoint SA3.1 preamp on the Net. Counterpoint SA3.1 .

I was a Counterpoint dealer and pretty sure that's correct.
