I'm not sure what size the fuse package is (I haven't looked yet) but 
assuming it is the standard 1 1/4" x 1/4", the Radio Shack catalogue number 
for 500mA @ 250v Slow-blow fuses is 270-1018 otherwise if it's the slightly 
smaller 5mm x 20mm size it is 270-1061.

This document explains the various fuse markings with respect to USA:

The actual meaning of the markings can be found on page 202 of the general 
document here:

Hope this helps.
