Nobody that is nontechnical should be going inside any piece of audio equipment and touching mains fuses.
This is an accident waiting to happen if someone needs to ask how to replace all his fuses for these orange voodoo fuses.
Some day somebody is going to forget to unplug the mains cord, take the lid off his equipment and grab that fuse with is fingers🤦♂️, it’s probably already happened we just don’t get to hear about it.
Are you then oregonpapa/SR going to put your hand up as say, it’s our fault?? I think not.
