How could the average person do this in 1959 or even now? I don't see typical recording devices coming with potentiometers (pots) to tweak playing speed. How could this be "induced" into a device of the 50s or even today? Could you place a potentiometer in-line with the current to change resistance and therefore vary rpms?
