If the relay fails the fuse should blow before the resistor burns out.

This probably same for Alpha 86..

Traced single wire from the 2A fuse to R10 - no other connections with that
wire
Indicates to me that the 2A fuse is in line with the resistor, should be
shown in line above where it is shown.
now to the question:
decades ago, some designer for Alpha must have thought that fuse would serve
a purpose.
I can think of a few pointless purposes but nothing that justifies adding in
the fuse.
ANY Thoughts ?
PS: Can't find other published designs that fuse the limiting resistor
