Check the belt is fitted correctly. If it is not it will affect the speed. If the speed is slow on both 45 and 33 rpm, then it could be the motor. Sometimes there are speed presetts at the none shaft end of the motor. If it doesn't look like the motor has any built in electronics in it, then look to the turntable power supply look for faults in that.
Jody, the arm the needle is on, usually adjustable with a dial on the end that can lighten, or put more weight on needle to help it track better on records. Other then that, the belts normally are changed to address slow speed issues. Check the attached links,instruction and guides, Good luck

Presumably you mean correcting the speed to play 45 and 33 correctly?
Some turntables have the speed control(s) as a preset(s) built into the base on the underside of the unit. Often covered with a sticker. You simply remove the sticker and stick a small screwdriver in the thing and turn it.
Others have the preset inside on a circuit board, got to by removing the bottom of the turntable. Others have it built into the motor itself.
You should replace the belt first if the speed is slow on both 45 and 33, before adjusting the motor speed.
A lot of turntables have two belt positions on each pulley. One for 33 and one for 45. I would check to make sure the belt hasn't slipped into the 45 position.
There are two possible causes, depending on if the deck is belt driven or direct driven. Sorry I don't know which with yours.
If it's a belt drive then the belt has come lose and should be replaced. Or the motor or power supply to the motor is faulty. Make a note of how the belt fits before you replace it.
With a direct drive it's either the motor or power supply to it that's got the fault.
Depends on if it's a belt drive turntable or direct drive.
If a belt one, there will either be a speed adjuster on the top of the motor, or one on a PC Board. And yes apart from setting the speed, it as straightforward as taking the old one out and wiring the new one in.
The direct drive, will also have to be adjusted for speed too.
My older Thomas Pacconi turntable was also turning too slowly. Rather than replacing the belt or needle, I tried using an eye glass repair screwdriver to alter the trimmers inside the motor. But the changes didn't take. Then I tried trimming the power to the motor using the larger trimpot next to the motor with the motor itself set to the 78 rpm setting. But the adjustments to the trimmer didn't get the platter to spin slow enough - it wouldn't play an LP. To get the speed down further I replaced the 1K trimmer with a 10K trimmer I picked up for a buck at Radio Shack and successfully adjusted the turntable down to down to 33 1/3 rpm usage. All that was needed was a soldering iron and a 10K trimpot to get the job done.
I have just fixed this problem on my Aiwa PX3800 with improvisation. The platter was rotating too slowly, I didn't know how much too slow only that the records sounded wrong. I imagined the belt, motor and platter as a bicycle gear and so simply increased the gear... I achieved this by winding a thin strip of a electrical insulation tape around the motor head to increase it's radius (like changing up to a larger front cog on a bicycle gear). I could then time the rotations and remove a layer or two of the tape accordingly until I have achieved a perfect 45rpm. 33 is still way out but I only listen to 45s! Be sure to trim excess tape from the motor head with a craft knife/scalpel or it'll stick to the platter. Poor man fix up.
Well, there isn't much on this unit that controls the speed. It's either your belt or your motor that's gone or going bad. Try replacing the belt first. If you still have the same issue, you might need to have a tech look at it. The 33/45 switches might have also gone out, but it doesn't like this is the issue.
