I had heard the story about phonograph needles jumping
out of the
track. It made sense to me. On a stereo phonograph record, in-phase
energy (L+R) is represented as side-to-side motion of the needle,
and out-of-phase energy(L-R) is up and down motion. It can also be
thought of as the left channel is recorded on one side of the
groove(at a 45deg angle), and the right channel on the other side.
It seemed plausible that a kick drum panned all the way to one side
or the other might send the needle into the adjacent groove.
It would be a pretty crappy turntable that did that! Probably a plastic
arm with no counterbalance with a worn dirty needle.
