You also said that pep output would not stress the fuse. I have seen MANY fuses fail from fatigue due to being run at or very slightly over their limit. Constant heating and cooling of the fuse in a dynamic power circuit such as pep service causes the fuse to fatigue from constant heating and subsequent expansion and contracting. It will eventually break free from the point it is soldered to the end cap. Sure it won't blow and you will need an ohmmeter to see if it is any good but it will fail. Eventually. Again.....stating the amp is capable of 750 watts in either pep or CW modes then saying that a 5 amp fuse will support full pep output is implying it can also sustain that same 750 watt power output in CW mode.
