[time-nuts] Standard Resistor oil

[paul swed]

What I have seen in the old text books is that these resistors all sit in a
tub with oil around them. The oil is at some higher temperature.....
I have a few of these resistors and no oil in them nor will I be putting oil
in them.
They seem to work to the limits of resolution of my test gear. 5.5 digit HP
meters.
Gud enough as they say. I do keep them on absorbent paper because they do
leak a bit even after 10 years.
