Most of the 'direct drive' turntables have a "pitch control" dial - you turn this dial until the black bars 'stop dancing' and hold still. There should be a little window with an orange neon light where you can see these black lines and adjust the speed. You may have to adjust it everytime you switch from 45's to 33's.
With a pressure gauge. If it's a home duty model it can usually be turned all the way in without damaging anything. Try turning it all the way in and fire it up. If the engine/motor doesn't groan or stop, you're probably okay. If the unit stops or slows down when gun is closed, immediately open gun, then shut down. With unit off, back off on unloader setting and set with pressure gauge, or have it done by a professional.
Some turntables have a pitch adjustment feature which allows you to speed up or slow down your records. The adjustment controller is usually a slider or a wheel somewhere on the turntable and is usually labelled "Pitch" "Adjust / Adj" or "Pitch Adj".
Please check for this feature on your turntable then get back to me if you are unable to find it. Please include the brand and model number of your turntable.
Pjam, Had the same problem & checked around on the net. Several people tried replacing the belt, but it had no effect. Spoke w/ several repair shops around the country and they concur with what I'd read on the net - bad motors. 3 or 4 repair/supply shops told me getting a motor would be impossible. Since I only listen to 33-1/3 LP's, I messed around w/ it a little and found a solution. Take the turntable out of the unit & you will find a small circuit board attached to the bottom. On that board is a small square blue fixture w/ a white circular "dial" in the middle (has grooves to accept a small straight blade or a phillips screw driver). This controls the voltage to the motor, which in turn controls the motor RPM's. If you set the selector switch to 78, you can experiment /w turning that white circular "dial" to slow the motor down. It isn't very hard to get the speed set properly. The down side is that you will only be able to play 33-1/3 LP's, but they are probably the most common anyways. I assume you could do the same to set the speed for a 45, rather than a 33-1/3. Down side is that you will only be able to play 1 size LP on the 78 speed setting, but it's an easy adjustment that can keep an otherwise in-op turntable functioning. Good luck!

Check the +10 / -10 slider too make sure it's not set to -10; adjust it towards +10 to the pitch / tone desired. Check the belt to make sure it is not loose. A loose belt will slip and turn the record slower than the recommended 33 or 45 RPM. Have a look at the YouTube video for correct set up if you're still having problems.

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.
Yes, shims are fine, but just remember, shims are prone to movement. Why don't you bring all the feet to their maximum setting, then adjust from there. Perhaps the table it is sitting on needs the shims?
