I'm not certain if you know this already, but the light that shines on the left side causes a strobe effect on the platter. One of series of 4 patterns will seem not to move when the turntable is at the right speed. To adjust this you need a record playing and then move the slider on the right till the pattern doesn't move. Which one not moving will depend on the speed selected and also the mains supply either 50 or 60HZ. You will get some variation in the movement, but you shouldn't notice the difference in the speed. If this is set up right and you still think it's slow, then you might have to look either right under the turntable or inside it. There might be on the underside one or two holes that might be covered up. They might even be labelled 45 and 33. If you find them you will need a small screwdriver and place it inside. This will turn a small speed pre-set. You will have to adjust this till you think it's right, with slight movements, testing with a record. If they are not present on the underside you will have to take off the bottom and look inside for a pre-set. Normally it will look like a 3 leg device with a screwdriver slot in the middle of it. Sometimes marked on the board "VR" with a number. Alternatively it will be on the other end of the motor. If you have trouble locating it follow the motor leads to the main board. Some turntables have two speed pre-sets others only one.
