The speed variations were similar to "flutter" that's common in cheap cassette tape playback...... The one instrument where such speed aberrations are most noticeable is piano......

For how massive that platter appears, the motor must be pretty powerful (or the belt drive pulley be very small in diameter) to generate the type of pitch stability I was hearing. Quick pitch variations are more common in turntables with relatively light platters. It didn't sound like "peak warp wow" (which occurs periodically with each revolution), but I wouldn't discount that either. (Peak warp wow is a sign of the arm being too massive for the cartridge compliance.)

I also noticed the LP itself was badly eccentric. Bad enough to see in the murky YouTube video. But pitch variation from eccentric LPs is most noticeable on the inner grooves. Not so much noticeable in the video because the outer grooves were played. (The speed variation is "sinusoidal wow" in eccentric LPs.)
