In exactly which unauthorized change ?
The ARCAM FMJ amplifier 32 does not make any Mod or change
Apart replacement fuse to fuse sold another million people like me
Check yourself before you speak
Just measure the current consumption of the amp with both fuses (but must be under identical conditions). You could also measure the standing bias of the output stage in a similar fashion.
Another test with no test equipment needed. From cold, fit the original fuse and play your music at whatever fixed volume you want for say an hour. Then switch off and allow the amp to cool fully. Replace the fuse with the special one and run the identical test again. Same music, same volume, amp in the same location.

What you said
i alredy done
I heard KEB MO SACD music the volume on the amplifier 20DB
I heard music 1 haur amp gets very hot
whan opened the thread the amp did not work for two hours and cooled
I changed the polarity of the fuse
I heard the same disk of KEB MO on SACD
Same intensity 20DB amplifier
And the amplifier is not warmed
The BIOS of the amplifier I I adjusted to 6 years ago the perfect level I'm not going to touch directions
For anyone
Exchanging a fuse for something which is not a fuse. It can't be a fuse because the effects you describe cannot be caused by a fuse.dazzz said:
I find it hard to believe that there are a million people in the world who will pay silly money for silly 'audio' 'fuses'.
It always amuses me that the most expensive audio upgrades available are those that can be fitted by users with little or no technical ability. Go figure!
Yes, as long as there's gullible people, there will be businesses to take their money.
SY's Fourth Law holds true once again.
Have you measured current consumption as mooly suggested?
It would be useful to have a scope to see if there are any oscillations.
I do, however, find it strange that a fuse could make such a difference. In a well designed amp fuses should make no difference.
With my limited knowledge of amp design I can't see how all these reviews stating improvements in sound have any scientific basis. All a PSU fuse does is limit the current (fault) flowing into the decoupling caps. The decoupling caps then feed the circuit.
And what is that diode symbol all about? Are there any pics of the internals about?
"BS baffles brains" in effect again?

It is a wonderful example of a little knowledge being a dangerous thing. People who know nothing will not change fuses as it is all too technical for them. People who understand electronics will only change a fuse when it fails, for a new fuse of the same (ordinary) type.
People who know a tiny bit about electronics will know enough to change a fuse but not enough to know that it doesn't need to be changed. These are easy prey for snake oil merchants. Some of them become snake oil merchants, or at least part of their willing army of 'botnet-like' marketing volunteers.

Probably tells you which way the fuse is supposed to be pointed. It would be interesting to see if they did anything weird - like using an intentionally rectifying contact, or a reverse bias diode in there in parallel. It would seem unlikely - if they did it would double the price. Try one with AC (like in series with the speaker) and intentionally blow it..... A $59 experiment... Take one for science?

So have you measured the current consumption using both fuses ? Was there a difference ?
As others have said, a fuse which is just a piece of wire chosen to fail at some specified current can not cause these effects.
If... if the amp really does behave differently with this special fuse, then whatever it contains is not just a piece of wire.
How about measuring any DC voltage and AC voltage across the fuse while the amp is working. But be careful ? And compare results between fuses.
Aww Come on Guys, he's getting upset now.
Have a look at the cheap amplifier and CD player he's using to test these things with.

The diode and the capacitor are the company logo that make the fuse, nothing to do with the internals.
Dazzz, as I said in an earlier post, a fuse is a safety device, if it is not working properly or is not acting as a fuse then it is IRRESPONSIBLE STUPIDITY to use the device, throw it in the bin and fit a fuse that is certified to work to the electrical regulations for the country you live in. At best you could damage your amp, worst you could cause a fire and kill people.
Now I am shure there are other super fuse users around, any of you want to give some sort of credible theory how 20mm of mains fuse could improve the could quality, 30kG of popcorn standing by.

It would be the only way to establish the level of BS. Do a "scientific" study on it...
I'm wondering whether this fuse is actually a fusible inductor. That could mess some circuits up and could change sound quality. maybe not for the be better.
I love reading the Snake Oil threads. One experiment was conducted over a number of days, the gullible idiots (aka experts) were told that they would be listening to different equipment every day. Obviously they weren't, the order of play was slightly different though.
Result. The equipment that came first on day one, didn't come in the top ten on day two.
Verdict. If you like Snake Oil, then drink a pint of it before any serious tests.

Has anyone done a resistance test?
In both directions of the fuse if higher in one direction a diode test with a meter?
Its simple to do.🙂
NB I don't use anti surge fuses with the spring. Just my choice.

You can get some weird fuse types, however I would give them a miss.

"This discussion reminds me of creationist arguments; no facts or logic required."
really?
or one could look at it the other way. ignoring fact and logic to get to the results you want.

😀..LOL
Echoplex delay..
No the reason is I watched one expand and contract on start up of equipment and thought its going to break the fuse element over time.
