I am well aware that the older carbon resistors often go up in value as
they age even if new. I always measure the resistors before I use them.
I do the same with the electrolytic capacitors.

That the oxide layer has degraded, and might be about to fail?

Could it have been possiable that the new resistor was bad, or maybe the
color code was read wrong so the wrong value was put in ?
As a lad, scratching through my dad's old box of mixed resistors,
looking for a near-enough value to one I needed, I used to get a strong
urge to choose any old value and re-paint the colours...

I find it amazing how I can spot a certain color code in a box of mixed up resistors.
I'm looking for yellow purple red.
Ah there's one.
