Expensive fuse or circuit breaker?

For the most part the toroidial transformer has replaced the traditional wax and paper transformer. There are some classic designs that cling to the latter. I I lack the technical expertise but I see no reason why we should still utilize fuses. In deed if you already own equipment it may be good idea to have it modified for coircuit breakers. This is especially true since it seems my fuse always blows at night or on the weekend when the store is closed.
What say you?

So if the fuse blows, it is usually technically defective, or the fuse is not correctly dimensioned. fast, medium slow and slow blow important.
these circut breakers have a heating coil similar to a coil, they have a magnetic effect which is very undesirable in audio equipment. Many manufacturers want more and more non-magnetic parts, e.g. ressistors. I wouldn't do it because I don't trust the trigger characteristics.

American ingenuity. Sounds like a solvable problem.

Sure don't use a fuse. When your device that only uses 2A goes to 10A and doesn't trigger tripping/clearing a circuit breaker and fries the device... you know who to blame.

I assume you are talking about a piece of stereo gear. If the fuse is blowing while the gear is idle then you have a problem. Better to find and fix the problem than modify the gear to not use a fuse.

i think you got it wrong or my english is bad. I use this Ahp module instead of a circut breaker in electrical distribution. It has the German VDE approval which which has very strict rules.

Yes I am.
IME when the fuse blows, it is because I have exceeded the power limit or there is a short circuit(loose cable or wire).

I am not advising anyone to modify their equipment. Doing so could void your warranty or possibly cause catastrophic failer. I am just wondering is that the general direction we should be headed. Given the prices of some fuses cost does seem to be an issue.

Indeed!--I'd hate to count up the $$$'s down the gurgler with blown so called "audiophile fuses"

Tried Hi Fi Tuning, Synergistic Research , Furutech, AMR, --all at the correct for the PSU T rated --disintegrate upon turn -on:mad:

Reapplying the factory supplied fuse --same rating and configuration --Unit fires up no problem.

My conclusion is seemingly these "after market" products have no surge capability--or am I missing something here.

Anyway I've given up -with the cost of these little b**gg*rs through the roof--I'm relinquishing spending any more hard earned on them

Meh!

;) Predictable results from taking advice you get off the internet.
