Found some at Home Depot a while back - they have some variety packs of off size small fuses.

EDIT: Here it is!
Fuse Assortment at HD
They got tons listed on the website as In Store Only items, so they should have it if that's not it

I needed one for inside of a printer - small glass one, sounds like it might be the same type.


Radio Shack too maybe:

Linky - fuse pack

Smallest one looks to be 3 amps though. Depends how bold you are...
