Do they change colors when they blow out?
The green indicates that this is a "fast-blow" fuse - so as
to prevent any damage to the electronic device.
A yellow fuse is a "slo-blow" - this allows the listener to hear the gradual audio degaradtion as the device slowly deteriorates, until the fuse finally burns out completely.
A red fuse is actually a jumper, not a fuse. It will not blow, rather it will continue to conduct as the device disintegrates.
Hey DUP, I'm sure that audio grade fuses have been discussed somewhere, but what about amps that have breakers that are sometime used in place of breakers.
Those color coding if you ain't being sarcastic, don't exist in the world of real electrical products. Usually a T embossed in teh metal ends for time delay. Yes, where are the "audio grade" breakers? There are HVAC grade, if you look at most ckt breakers 15, 20A. they would have HACR printed on them. that is a NEMA standard, It means the breakers are useable for heating Air condionting Refrigeration. a recognized standard....the re are no "audio grade" markings on breakers, fuses etc. Why are they allowed to market and advertise under basically FALSE claims. There are also certain breakers and switches rated for H.I.D lamps....Breakers when used to switch H.I.D. lighting ckts, as the usual swithes, have H.I.D. ratings. No such Audio lableing, same for wall outlets, and cord caps. How much money do you think is spent on ads that make false claims as to "audio grade"? Hope the FTC is tracking it all, maybe a nice big crackdown on these companies making adbsurd claims. hi End is doing itself in, with nonsense.
Mike,Dup can't answer this since AVA use fuse.The amp i own has a circuit break and here's a letter a received from the manufacturer when i bought it.
Dear customer
Thanks for purchasing our product.Since we use a breaker instead of a fuse,we are going to send a lady together with the amp.Please,state how you want her,"slow blow" or "fast blow" ?
Reagrds....
DUP,
My comments were all tongue-in-cheek. In years past, though, I have repaired power amps that had breakers, as opposed to fuses, in the power supply. I have also seen amps with thermal fuses attached to the heat sinks, of the outputs. Were they '"audio grade"'? I doubt it.
So as not to offend anyone, I'll refrain from commenting.
On a more serious not Dup.its those little bits-and-pieces that when you add them all up make a good sound.
