Help identifying SAE 5000 fuse amperage

[Yodathedog]

I have a SAE 5000 that is missing its fuse holder cover. I just got one from a seller on ebay, but I don't know what size fuse to use. I've looked for the service manual and was only able to find a manual for the 5000A, which apparently doesn't have an external fuse and makes no reference to one. To compound the problem, the new fuse holder came with an array of fuses, none of which I wish to blow needlessly.

Any help is greatly appreciated as usual.

Back of my unit says 1/8A by the fuse. It would be regular, not slo-blo. The unit doesn't use a lot of power.

Thanks very much for that. The paint on mine was a bit rubbed off. Any idea how to separate the cover from the body?

lemme look, I know I have been in it as I have bypassed the fuse since it is without a cover and installed an internal fuse.

Looks like the sides come off then the knobs come off and the board pulls out of the unit. I don't recall if the jacks stay but once inside you keep pulling screws until the front comes off and the board comes out. IIRC
