My comment,
Oh well......was in response to your comment.
Try this type of slo-blo fuse in your power amp/s. It has built in wiggle room.
Believe what you want, next time you switch on a high current draw amp, see if you can see the resistive element inside the mains fuse move and bend a little.Get it, "wiggle room".... Humor....
