I just recently bought a new turntable, and when it plays my LPs, the LPs sound somewhat slower than the original. Does the slowness have to do with the belt of the turntable? Is there anyway I can fi

If the 45's play OK then your belt might not be fitted in the right place. If they are both slow, then either the belt is slack or the drive is faulty.

More than likely your motor might be bad. There is nothing else that controls the speed. Are you sure you purchased the correct size belt? Turn on the unit, without connecting the belt, and touch the motor shaft, and see if it fluctuates. You can also just get a marker, and marker a point on the motor shaft. When you turn it on, it will act as a visual indication as to it's speed.

SOURCE: sound wavers (speeds up and slows down)

you need to replace the Pitch controls. I'm presuming it is a sliding pitch control. Use the Red start stop lights that reflect on the rotating wheel. put the pitch in center 0. does one row of the dots on the wheel stay completely still.now just turn it up op down a bit until it starts to move the dots slightly. now watch the dots now while there moving. Do they fluctuate they should be smoothe. do this on both decks to find out which one is fluctuating.

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!

SOURCE: JVC Turntable model AL A1 BKX , need to know how to adjust speed

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.

How do I fix the speed of my Jensen JTA-460 turntable? I've tried numerous records that previously worked perfectly, but now the speed is too slow regardless of what album I try.


Could be the belt for the pulleys is stretched a little, or there is something making it slip, or the potentiometers were set incorrectly from the factory . It is normal to have one for each speed. It is unknown if you can access these from the bottom of the unit. Slippage is less likely to be caused by something oily, since it would alternate the speed faster and slower and yours seems to have worked then reached a constant slower speed. Do your 45's and 78's play ok? (yeah I know, does anyone have a lot of 78's on hand)
Your model does not have an outside pitch control to fine tune the speed faster or slower. Another Jensen model JTA-230 does. Entry level turntables such as yours are not speed accurate reliable. After reading reviews on your turntable, it's possible that the belt is the problem. If the slow speed problem had happened from the start, it would be safe to say that the speed wasn't calibrated correctly and you could have returned it and perhaps had better luck with another one but because it worked fine at the start and then now plays slower, it's either the belt or the potentiometer for the 33rpm speed has somehow changed.

Why is my brand new crosley turntable keepsake hunter skipping tracks?


The turntable may not be level. Also, the stylus could be damaged or defective. The stylus pressure may not have been set correctly in production or may have been affected by shipping.

My Jensen JTA 450 is playing LPs too slow even though 33RPM is already set. The songs are slower than usual. Please help me.


The record that you are trying to play maybe a 45rpm recording. Some 45's were released in album size recordings.

VINYL PLAYER SLOWS WHEN I STACK A COUPLE OF LPS sounds funny play fine with just 1


The labels on the LP's stick up higher than the vinyl. These slip on each other when you stack LPs.
One LP sits directly on the turntable mat and has enough friction to turn.
The only solution I can think of is to put something 'tacky' on the labels but this might be detrimental to the label.
