It's not original - or at least there's no fuse in the schematics for the
AC input path (which is what the yellow wire is part of). I don't think a
manufacturer would leave a fuse just flapping about in the chassis like
that, either (although having said that there's a 120VAC distribution panel
on the outside of the case at the back with no indication that it ever had
any kind of cover)
As mentioned in another post, this is an automotive 'scope; what I like to
imagine happened is that some apprentice, perhaps in the early '80s,
complained about having to use such an old device which didn't even have a
fuse, and so their boss did this as a joke, showed it to them, and then
told them to just get on with their job (possibly with a good slap on the
side of the head) :-)

protect the fuse...
I hope everyone here
knows that this almost certainly will open the fuse
with such heavy soldering. Buss made fuses with tails on them that would
allow you to direct solder them into a circuit.
This is of course a joke, but the heavy handed soldering job makes me
wonder if the fuse ever did anything at all. The manufacturer would have
been at fault to have put it in in the first place with direct solder in
the yellow wires.I am thinking of a late night scenario in this case with
one of those nifty Weller 500 watt guns that could be used with copper
water pipe and delicate electronics, and someone with no idea where fuses
came from.
