[QUOTE="Ampdog, post: 809451, member: 144"] Further to Stanp's explanation: Fuses are not precisely specified things; they have a tolerance. I have never noticed that stated somewhere, but can look it up. But to use the opportunity yet again to get some perspective on the matter, any voltage drop across a mains fuse is negligible, particularly ai a circuit where the applied voltage can vary by some 10% -20%. The sparks usually have a habit to come flying regarding loudspeaker circuits. Yet again if the fuse plus contact resistance is compared to the total resistance in the circuit, the effect might reach some 0,07dB. (Frowning? remember that the total series resistance in any loudspeaker circuit can be no lower than some 6 ohms for an 8 ohm driver: the d.c. resistance of the voice coil. Strange how often that disappears from the circuit during some discussions and calculations, particularly with regard to the so-called damping factor .... ) [/QUOTE]
