Thanks! Yes, that looks very similar except mine has a tolerance rating
of 10%. Vincent helpfully pointed me at:

which look like they should do the job, and I ordered a handful just in
case I ever need a few more.
Thanks again,

Yep, that was me looking for the same part. Does yours look
like this?

According to Onecall Farnell 'a blue band at position 5 indicates 20%
tolerance' which would make it a tolerance multiplier of 2.
However the only ones they sell are 5% tolerance, ie brown-black-gold-gold
not brown-black-gold-silver + blue, but the technical chap I spoke to seemed
certain these would be ok. I bought 5 just in case.
Onecall are education-only suppliers but the same part numbers work with
Farnell/Element14. Part# is 1692450.
It's listed in the print set as a 1 Ohm, 2
Watt resistor, with a "FUSE"
designation. I'm not entirely sure what I should be searching for for a
replacement; clearly the "fuse" part of the designation is important but
I'm not sure what a modern equivalent is. I've browsed around Mouser
for awhile and I'm not seeing anything obvious. I'm sure this is
obvious to anyone with experience -- can you point me in the right
direction?
There was a recent discussion here about a similar component in
a VT100 supply. I think a suitable replacement was eventually found
at Farnell/Newark.
