Turntable plays too fast

The turntable plays records too fast - the record's pitch is noticeably higher than is normal.

    I have a SL-A100 and I have the same problem. Actually, it's not that the turntable gets stuck on 45 rpm when I switch to 33 (which is what your solution seems to fix). It just rotates *slightly* too fast: it actually spins at 34.7 rpm instead of 33.3, enough to raise the pitch of a record just shy of one semitone. This is exceptionally annoying that a recent product like this ships with such a trivial defect.

    We have a GPX brand turntable. It plays to slowly. Can this be fixed?

    i had the same problem with my teac sl-a100 that i got in the garbage. it was stuck in 45 speed making turbonegro sound like a chick-punk band. although that was enjoyable, i took off the top and lightly oiled the belt driver. after putting it back together it worked perfectly.

I have seen this problem before. Lift the turntable off. It might be held down with a clip around the center pole. Under it you will see a wheel that contacts the turn table and the center shaft of the motor. The motor shaft has 3 0r 4 elevations with different diameters. When you change the speed the wheel will move up and down to different diameter levels on the motor shaft. It must be free to move. It might need some oil at the moving parts as I suspect it is not moving properly.
Hope this helps.

Mine was playing too fast. After exhausting all options, I found a solution that worked perfect. My motor shafts that powers the belt is thicker in the middle and thinner above and below. The belt would always seek out the thickest part, no matter how I adjusted it. It played faster on that thick part and slower on the thin part. I simply shaved down the thick part a little. It took a couple of times, having to put the belt on and off to test it. I would let the motor run & used a sharp screwdriver to shave the metal drive shaft/rod down. It plays perfect now.

Electro Brand model number 9801: I played one record, now when I tried to play another the turntable will not rotate. Could the motor have burned out that easily?


Listen carefully with your ear to the turntable when you move the tone arm towards the record. If you can hear the motor running and the turntable is still stationary then the drive belt from motor to turntable has probably fallen off of broken. Lift the turntable, there's normally a metal clip holding the turntable in place, and locate the drive belt.

I got the unit(gf-350)home from the store and set it up.at first it worked okay..but only for about two hours.i noticed that the cd's were getting unusually warm after being recorded on.after about two...


It sounds to me you have manufacture defect, you said it worked fine for two hours and then you ran into problems, if there were issues with the cd's they would not have played. I would do yourself a favor and return it for exchange or for a different unit.

I have a Philco Classic ... the turntable did not work. I pulled the arm back, as suggested, and it worked! But it really drags when I try to play an LP. What now?


what do you mean it drags? I noticed if you don't pull the arm back far enough,it will turn on,but the arm will drag foward scratching your record. Try pulling it bacl ALL the way and then it should give you no problems.

Rca record player is playing slowed down or sped up


Hi there

this sounds like the belt that drives the turntable itself is slipping you can normally access it by removing the securing clip by the centre spindle and then lift the turntable up and you should be able to see the belt give the belt a good clean with isopropyl alcohol refit and hey presto (if you still get slippage order a replacement belt )

Record player sounds scratchy and tinny


Playing records is a contact sport.

Since the needle touches the record -- as opposed to a laser reading a CD -- any bit of dust or mold translates to annoying pops and hisses.

Record cleaners get down into the record grooves to extract dust and particles.

Or you may need a new needle.

Turntable Spinning too fast

Turntable not turning to play record............. power on............ please help my email address - diatmesa@aol.com


This could be many things like the following>

If its a direct drive turntable the motor could be "blown",
or motor electonic speed controller burnt out.
If its a belt drive turntable then the belt could be broken
or stretched and is slipping, or the belt can have dropped of a drive pullety.
Also there are speed control mechanisms to adjust the final speed of the
turntable to the recorded speed of the record like 331/3rpm, 45rpm 75rpm
These speed reducing mechanisims can slip and cause the turntable not to turn..
There are also other mechanical bits that slide and push against each other,
and these can get sticky and the friction increases so much that the power
from the motor drive causes the belts to slip, so you need to identify if a
friction problem exists as well..

If you are carefull you can look your self and find out which one of the above it is.

Be warned there are lethal voltages inside the turntable which can kill you....
so please dont have the power on when making any inspection or adjustments.

Cheers From YUBEUT..

Philips turntable af 829


Specifically the turntable AF-829:
I had exactly the same problem, and fixed this succesfully.
The problem is in one of the opto-coupler combinations (LED + LDR).

There are two, both located in the mechanical part of the turntable:

1. The first is for the detection when the arm reaches the end of the record, so that it will return to base. This is a red LED with an optocoupler in a little black case. This is OK.

2. The second one is for detection that the arm has reached the beginning of the record area. You can test this by manually pulling the arm from base and moving it towards the record. Then the turntable should start to rotate. You will see it does not.
The problem is that either the LED has not got enough light-emission any more, or the LDR has become more insensitive. It's a transparent LED that radiates RED light.

I replaced the LED by a new (red) one with higher light output, and now it's working fine again.

Good luck!

Marcel.
