I would post this in the basics group but it seems like there are more
responders here. Anyway, I have been looking at DIY single ended tube
amp schematics recently. These are modern schematics using grounded
power cords. And several have in common that the power switch is in
the neutral line and the fuse in the hot. Wouldn't it be safer to have
both the switch and fuse in the hot line?
Thanks,

For a 3 wire power system (with grounded chassis) that is incorrect as
you suspect.

For a two wire power then it is correct to have the switch on one side
of the line and the fuse on the other as you don't know (unless the plug
is polarized) which side is hot when plugged in.
