Suggestions?

The first job you get as a tech in Bell Labs was inspecting the wire wound
resisters lines. Using a form of thin Nickel chromium wire as a resister gives
you a predictable outcome based on the length of the wire used. Wire ends are
spot welded to the terminals. Spreads heated area out a bit for better cooling.
Will be
bigger than some forms of resistor. Can be mounted away from heat sensitive
components. Not very sensitive to momentary over voltage episodes. Some designs
can be held to the center of a spec at little cost. Let a little air get to them
and they are reliable as a stone.
