The designer of K's pre amp more than likely did the standard type calculation for the fuse. There are safety reasons for this and I know of no reason that these standard type calculations do not apply to a low current device and it seems to me, unless the designer made a mistake that putting in a fuse 2.5x higher rated than the person smart and well trained enough to design a commercial pre-amp would not be too kosher, unless I'm missing something.

It's not so unusual to use a more readily available 500mA fuse rather than a 200mA fuse.

"Look at the 20VA transformer in the table. Short circuit current is just over 2A, and full load current is ~170mA. This ideally requires a 200mA fuse, although a more readily available 500mA fuse will work."

  What is usual or unusual is not the issue. The designer calculated for a 200ma fuse, not a fuse 2.5 times that current rating. Your example states that the 200ma fuse would be ideal. If 500ma would work as well as a 200ma fuse for protection than why would anyone use a 200ma fuse? It's not all that unusual for people to believe that the sun revolves around the earth. Apparently 26% of people in the US believe it. I could come up with one or two more examples of irrationality if I thought hard enough. Tweaker456

    Give it a rest. You can beg to disagree with anything you wish to, but there is no great rule being broken that deserves your complaint to the moderator.
