Because while I have never measured the full current draw of a K100 there seems to be inaccurate fuse ratings for these amps.
For example in the schematic for the K100-5 ( the PA head ) the fuse is shown as 1.5 amps while all other K100 heads are shown with a 3 amp fuse.
A 50 watt amp ( which these really are ) does not need a 3 amp fuse.
If you look at all the k200B heads they all use a 3 amp fuse, yet have twice the output wattage as a k100.
Try the 1.5 amp fuse and play the amp loud to see if it pops, if it does there should then be no need to go any greater than a 2 amp fast blow type.
With a 3 amp fuse in there if there does develop a power supply / output stage problem then a bunch more parts will blow up before that 3 amp fuse lets go.
