You have answered your own question. The fuse won't blow until 2-3 minutes
key down (assuming a 5 amp fuse). Those breakers work in milliseconds.
While on the subject, you ought to know that Ten-Tec does not stock
replacement finals for the Argosy. Presently they can get them at perhaps
$40 each (not sure about the exact price). A $10 buck investment in the
breaker seems wise. But on the other hand, you may be happy with your fuse.
