This is mainly just a note to myself, since I can’t seem to get it through my skull, but IC pints are numbered counter clockwise. Not clockwise. I just wired up an IC backward, which I had previously done before when trying to repair a multimeter. This time, it was on an op-amp I’m using in a frequency standard (which I’ll post on later.

So, see the picture? Got it? I’m such a dumbass sometimes.
