Anyone replaced Fuse with Circuit Breaker?

Ryanvt, this is all new to me. I haven't heard of any breakers for audiophile gear like your speaking of. With the breakers I've seen, I don't see how they can make a more solid connection than a fuse whose connection is solid inside. No breaks in a fuse that can make noise. I wouldn't know where to begin on recommended a breaker to replace the miniature fuse in an amp, especially one that can maintain a more solid connection.

In the '60s or '70s, I remember companies started using breakers on TV sets. They called a lot of them "reset" buttons. These were mass production, and I imagine they tried to save every penny making them. Then about the time they went all solid state, they went back to fuses for some reason.

Even the new D'Agostino amp appears to have a standard fuse on its case back. Link [http://www.dagostinoinc.com/]

I would like to provide info if I could.

Magfan, I'm familiar with the dual magnetos required for piston powered planes. Double needed to stay flying if the other fails. I'm also familiar with different ram air turbines (RAT) needed for a lot of airplanes, for hydraulic and electrical power. I don't see how any of this will help the OP though.

I have not used a circuit breaker (I'd probably electrocute myself), but I CAN suggest HiFi Tuning fuses (I got my first ones 3 days ago, and MAN, did the purify the sound ("purify" in this sense means ridding the sound of grit and significant amounts of grain, lowers the noise floor (!) and improvements imaging, soundstaging and precision of image improvement. And those are just the audiophile things! Musically, a flute sounds woodier and the cello and double bass are particularly noticeably better in pitch and weight. And lets not forget the microdynamic improvement (part of the lower noise floor, which lets subtler information be heard). Try them out first. Circuit breaker later!

Invest in the Hifi Supremes.

I used IsoCleans when I had a pair of Classe DR 8's and they made a nice improvement.

You won't regret it.
You'll have protection and better sound .

You know, Lacee, I'm wondering if part of the reason the Antique Sound Lab Hurricanes were so prone to blow resistors could be a function of the original fuses, which were, of course, inexpensive. I don't know, just speculating.
Back to the HiFi Supremes.

I am continuing to be astonished at how much "cleaner" the sound is with the Supreme in it (only one amp has it in it: the other is on its way). I have Tube Traps (around 40 of 'em) and it is SO easy, now that the Supreme cleans up any "fuzziness" or "halo"-effect around instruments, to tell when the sound is an improvement or a detriment (meaning: you can turn a tube trap 1/16" and kill the transient or you can, equally, improve the clarity of the transient). Also, the ambience AROUND the instruments is so much more easily discerned.
I've only had the Supreme in one amp since Friday (December 30th). A friend of mine, Dave, who loves Scheherazade, listened last night and was puzzled that the highs seemed diminished, but that the midrange was gorgeous. We later traveled to another city for New Years Eve, came back today, and I went into my room and listened again. Movement 3 has some triangles around 4:45 that, prior to today, were somewhat muted. When I listened a little while ago, they were much more audible, and no changes were made in the interim (including moving a Tube Trap, which could also make the highs more audible if turned, as I said, as little as 1/16"). I just sat down and listened and the transient AND the harmonics were unambiguously clearer. I can hardly wait for another 72 hours to pass. I fear to see the electric bill, though...
