Getting dictaphone motor running smoothly

Post by kirtley2012 »

I've got a phonograph I'm putting together with a dictaphone electric motor.

The motor is coming off a transformer to bring the voltage down and through resistors so it doesn't have infinite current but I'm having a warbling problem whenever it is brought down to speed, it's not the pulley or belt, could it be the governor?, I'm struggling to think how to solve it
