My first record player at the age of fifteen, was actually a pre WW2 table-top phonograph. It only played 78s.
There was a speed adjustment that allowed you to alter the speed slightly with a sliding lever.

So I had a look inside and found that all this lever did was to apply increased pressure on three felt pads that rubbed on a flywheel, there was also a gimble that governed the motor speed. All I had to do was to remove the screws at either end of the plate that restricted the movement of the lever. I was then able to slow it down, to any speed I chose, but had to guess what was 33rpm and 45rpm. Whatever speed I selected, it ran at a constant number of revolutions, no "wow" at all.

I also changed the pick-up arm and cartridge. I had it for a year and didn't set the house on fire once.
