33 Records are playing a bit too fast on my Wockoder Record Player... Is there any way to fix this?

Lots of quality turntables have a speed checker and a limited amount of speed adjustment.

Many ordinary record decks use a synchronous motor, the speed of which is regulated by the Hz of the mains supply and with mostly fixed gear ratios it is impossible for them to run faster - slower is the usual problem.

I expect there will be types driven by a dc motor and regulated by a switch mode power supply but I know nothing about them.

I suggest you begin by learning something about your turntable.

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.

How to fix flutter & wow on a Gemini 500 XLii direct drive turntable

Direct drive turntables have electronically controlled speed. If the records you are playing are warped (not flat) that will cause wow & flutter. If that's not the problem then you might try connecting the turntable to a different power outlet using a long extension cord. Failing that, the turntable needs repair.

How to tweak the playback speed on Panasonic SL-HM42 turntables
recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-20.png

You will need:

  1. 1x small Philips screw driver
  2. 1x small flat-head screw driver
  3. An ear for correct pitch and a little bit of DIY skill!

Step 1 - Remove the wooden base plate

After ensuring that you've removed the the rubber turntable slip mat and securely docked the turntable arm, carefully flip the turntable over onto its lid to expose the wooden base plate, as per below.

Using the small Philips-head screw driver, remove the screws holding the wooden base plate in place, then gently lift the base plate off the turntable.

Step 2 - Expose the pitch adjustment screws

Once the wooden base plate is removed, you will see the speed-controller circuit board on the right-hand side.

To expose the the two speed/pitch-control screws, firstly remove the screw holding the speed-controller circuit board in place, then gently lift the circuit board up on the free side.

Step 3 - Correct the turntable playback speed and pitch

The easiest way I found to correct the playback speed was to flip the turntable carefully back into the original position, allowing the speed-controller circuit board to hang free as shown below.

recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-60.png

Next, play a record that you know well and are able to tell when the speed/pitch is correct (assuming you have an ear for correct pitch, that is!), then at the same time using the small flat-head screwdriver, gently turn the speed adjustment screw(s) to adjust the playback speed up or down until the correct playback speed and pitch is achieved (or at least until it no longer annoys you ;).

Turning the screws clockwise (to the right) will increase the speed/pitch, and anticlockwise (to the left) will decrease the speed/pitch.

NB - Both screws allow for fine pitch control, so if the second is already at maximum speed, you can use the first screw for additional speed.
Step 4 - Reassemble the turntable again

When you're happy with the speed of your turntable, remove the record, the mat again & locking the turntable arm, replace the screw holding the speed-controller circuit in place (as per Step 2) and then finally replace the screws holding the wooden base plate, as per Step 1.
Happy listening!

How to adjust AIWA Turntable PX-E860U speed

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!

My records that are 33 and 1/3 don't play at that speed on my turntable. they sound more like a 30 speed, what do I do

Hello Rosie,

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.

Hope this helps.

Regards,
BElectric

Akai Ap-003 belt drive turntable pitch problem

Hi!
Make shure that is a 50Hz turntable. If you connect a 60 Hz turntable in a 50 Hz system, the result is aprox 28 RPM in the 33 RPM position/

One of my technics' 1200 turntable's tone gets too high

You can try adjusting the pitch's gain, which is located on the pitch control circuit board. Only problem is that you'll have to take apart your turntable in order to get to that section (its on the bottom).

If that does not work, your pitch might be bad, or one of the main circuit drive IC's might be bad.

Hope this helps some.
