These are most likely just pico fuses, however Hitachi will not reveal the amperage. You will find they are expensive, however I stock all sizes of them and as usual I try to stay with the manufacturers original part. They can be ordered from Tritronics and if I remember correctly they are around $3 each. When troubleshooting I solder a pigtail fuse across (just for troubleshooting). Then when all repairs are completed I replace with original part.
