There are a few other possibilities. It could also be the amp, or one bad side of an RCA cable is loose, or damaged inside.
The cartridge I received doesn't explicitly specify where each of the ground wires goes, so I connected the left and right channel connections to the appropriate positions and then tried the two possible combinations of ground connections. Neither of these resulted in any change in output. I also tried tightening the sleeves around which the wires are enveloped (in case the connections were loose), but this had no effect.

We can work out the possibilities from there.
I tried this and the dead channel did switch!
Would this decrease the probability that it's a problem with the amp?
I also wouldn't say the channel is absolutely dead - there seems to be noise coming out of the channel, it just doesn't seem to be amplifying the audio signal from the vinyl.
