Did some experiments on the fuse of my amp... I replaced
a 500mA 250v fuse with a 1.6a 125v fuse and found the
sound much improved. Then I decided to replace the 1.6a
fuse with a jumper made of a silver paperclip, and found
the sound improved much further. Then I replaced the
paper clip with silver solder, and found it improved
further (though I'm less sure about the solder being
better than the clip overall...).

Question is: Exactly what risks are there in running an
integrated amp or a preamp sans fuse? I don't care so
much about the gear blowing up, since its old gear
anyway. But nor do I want a fire started when I leave the
amp running all night or am not at home. In the case of
the preamp, the casing is solid metal, with the
integrated, its a wood casing. What are the chances of
fire and how would it start? What are the chances of it
blowing up and how might that occur? (so far, no
problems!). Is electrical shock a risk with a fuseless
amp?

Good question for rec.audio.opinion. Ask for Middius.
