<p>I think what happens is they absorb moisture over the years,
which makes the substrate material expand, resulting in resistance
values increasing. A gentle baking might bring them back into spec
- but for how long would be anyone's guess. Put 'em in your boat
anchors and keep them warmed up on a frequent basis...</p>

<div style="font-family: Arial, sans-serif; font-size: 14px;">I
still have parts cabinets stuffed to the top with these and I
test the entire drawer when I need to take one for a repair. A
lot of the really, really old ones have drifted way beyond even
their generous 10% tolerances of their day. A surprising number
of them are still good, though.</div>
