[Boatanchors] [BoatAnchors] Carbon Comp Resistors: The Darkness Gathers?

[Donald Davis]

Resistors do change value after years of storage / years of use.  Re burn-in
at 150 degrees F in light roughing vacuum for 24 hrs or more. If they are
not stable after this, toss them.  If they're OK, try and store in a warm
low humidity area.   Might consider conformal coating.  This info is from 35
years of aerospace engineering and assembly experience.  Yes, we used carbon
comp resistors in "legacy " hardware in the '70s. 73 de don ad6pb
