I recall reading more than once that the actual numerical rpm choices were the result of gear drives. Before the mid-40s the gear drive was common. 33, 45, and 78 are all whole integer gear ratios. I have never done the math. I assume that there was some sort of motor shaft/rpm standarad that they were stuck with.
33 rpm was already the standard for transcriptions and sound tracks. It is not the ideal speed for LP and has been a curse from day one due to the inner groove distortion.
Once again, I have never done the math. I read this. Mark
