I have fifty 910 ohm 1/4W carbon composition resistors, still in the
paper tape, which is labeled:
OHMITE
910 OHM
1/4 W 5%
RC07GF911J
OC9115
Judging from the last line, they're 14 years old. They've never been
used, AKA New Old Stock. Every resistor measures greater than 5%, some
are over 1k. Over 14 years, would drift from aging cause them to go
that far out of tolerance? I have carbon film resistore much older than
these and they still measure within 5% tolerance, usually within 2%.
I think this is common.

I bought a box of 1000 114 ohm resistors. Stackpole Mfg Date 1980.
Unfortunately, they're marked 100 Ohm 5%. Was gonna use 'em
in pairs to terminate 50 Ohm transmission lines...oh well...
I should try cooking them to see if they change back.
