[GreenKeys] Loop supply rheostats

[hwhall at compuserve.com]

Recently, there was a brief discussion of having variable resistors in the loop, to tweak the loop current.  With that in  mind, today I came across a box of brand new rheostats marked 2500ohms, 0.1amps. They have screwdriver adjust shafts.  Anyone want some of these?
