I have fifty 910 ohm 1/4W carbon composition resistors, still in the
paper tape, which is labeled:
OHMITE
910 OHM

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.

Hey, YEAH! Great idea! I'll hold a couple over the soldering iron and
see if they stay changed when they cool off. It won't hurt to mess up a
few, since they're already messed up to begin with. ;-)
BRB...
Well, that didn't help. I took four of them and layed each on the
soldering iron. Each went up several dozen ohme, some between 1050 and
1100. And they stayed at that value when cool. :-(

It's been a long time since I did the math, but IIRC, when you added up all
the tolerances, milspec carbon comps could vary in-circuit by 41.4% of their
stated value and still be within spec.

Is that right? How do you account for this:
http://www.sonofthesouth.net/leefoun...es%20slave.htm
I can't find anything in a cursory online search about Jackson owning
slaves, but his family certainly did:
http://en.wikipedia.org/wiki/Stonewall_Jackson
....as was JEB Stuart:

Don't know George Johnston. If you mean Joe Johnston, I can't find
anything online with another cursory search. Not going to try very
hard; the side he picked speaks for itself.
