The guru on fuses:

@georgelofi : you state,

"He's probably the dumbest of all the fusers here, as he "tries to justify" his stupidity".

Good one georgie boy, advocating for displaying stupidity with reckless abandon.

What you need to strive for is 'wreck-less' regarding the damage you do to a thread!

@danvignau - thanks for the link to the article, I've not seen that before.

The fuse he was talking about was in the speaker circuit, not the power circuit.

+1 @audio2design. 

The text on page 6 refers to protection of the amplifier outputs i.e. the signal that goes to the loudspeakers. There needs to be protection at this point in case a fault in the amplifier sends DC to the loudspeaker drivers, which can result in quite spectacular failure. Loudspeaker protection needs to be very fast (milliseconds) which means any fuse would need to be rated very close to the maximum operating current of the outputs and it would heat up in normal use creating distortion.
Most (if not all) amplifier manufacturers use alternative methods to protect the output... I use relays, others use transistors etc.

The fuses that most people in this thread are referring to are power supply fuses which will not heat up in normal operation and can be rated with comfortable headroom above the normal operating current. These do not form part of the discussion in the article.

Thanks.  I had not considered that people are discussing inline speaker fuses.  I still wonder if most people are.  I did use fuses to protect my stacked Advents from my Phase Linear 400.  A dropped tonearm always blew them. 

danger2audio you are as wrong as usual. Tom

I am curiously noting that you're not providing any links :-)
