I have not used it in a long time seems like the speed is wrong when i put it on 33/1/3 plays slow when i put on 45 it much better playing the 33

Check the videos as there is an adjustment. Also check for slipping belts.

Try moving the speed switch from the 33 1/3 position to the 45 position.

Hope this helps.

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.

That is a belt drive unit. If there is no speed adjustment. You need to take the platter off and check the capstan and belts.

You may be experiencing Acoustic Feedback, although it doesn't really make any sense the way you describe it. Make sure the tonearm is balanced and the proper weight is dialed in on same. Does it make any difference if the volume or bass are turned down, which my point to the Acoustic Feedback.

Found this post trying to troubleshoot my Aiwa PX-E860U-after replacing the belt and lubricating bearings, the speed was off. 33 setting was playing slow. Here's the fix:
1. unplug and flip upside down
2. Locate the two holes marked 33 & 45 where black dots are visible underneath
3. Using a very small flat screwdriver(I used one from an eyeglass repair kit), adjust the speed clockwise for faster, counterclockwise for slower

this is a DIY solution, so not perfect, but it works. I played the tracks along to a Spotify recording to get a good match. Hope this helps someone else!

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!

The cartridge must have a stylus for 78rpm records. If the turntable does not have a 78 speed play it back at 45rpm. Record it and using the software you have or get one such as Audio Cleaning Lab, just select the option to convert from 45 to 78. You can then carry out any audio modifications to clean it up, then save it as an MP3.
Never use a 45/33 stylus to play a 78 and never use a 78 to play a 45/33 record.

I had this problem. In my case it manifested itself mostly in start-up, and I found that I had to move the tonearm past the 1st track to get the TT to spin. I cleaned the contacts on the micro-switch (on the mechanism, from below) with extra-fine sandpaper. It worked.

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.

Hope this helps.
