Question about Audio Players & Recorders

Open Question

I have a Sansui SR-525 turntable. Problem is that when operated in either 33 or 45 rpm positions the platter spins very very fast. The two adjusting knobs on top of the unit have no effect. Either do the two potentiometers mounted inside the motor. All potentiometers have been cleaned and deoxidized. Note: there is no speed control assy mounted under the platter for this particular model. Thank you

More than likely the drive IC (integrated circuit) has shorted, and needs to be replaced. Not an easy fix, and you'll have to take it to a service center for replacement.

This is a common problem on this turntable.

SOURCE: Dual 1228 turntable platter not spinning, the motor will not turn

This particular unit uses an idler wheel to drive the table. Remove the platter and check the rubber wheel. It may be dirty, or just dry and slick. This part may need to be replaced or treated.

SOURCE: sony ps-lx2 turntable clicks when spinning

It seems something may have come loose over time or history, but you will have to delve inside to see what it is. It sounds as though the fault should be obvious.

If you do not want to do this, a repair shop should have no problem. I assume that the deck is working ok otherwise.

If the turntable has a two-piece platter, Lift off the outer platter and place the belt around the inner platter and motor pulley.

If the turntable has a one-piece platter, lift off the whole patter, place the belt around the inner drum. There will be a hole in the platter's top through which you can reach a finger to stretch the belt so that the belt can be placed around the motor pulley as you put the platter back in place.

My turntable won't stop spinning


It can be only one of two issues. Either the micro switch that should shut it off is defective, or the linkage that operates it is out of position. For more information, please visit my website at audioserviceclinic.com. Thank you.

Grundig 4400 / Audio Techinca T4P Turntable spins at 35 RPM instead of 33 RPM


I think you mean 45 rpm?
It sounds like you have got the belt in the wrong position. Try adjusting the position of the belt by experiment. Or you could look up the correct way to set up the belt.

Platter/motor won't turn


I don't know the answer, but you have written one of the finest, most comprehensive problem descriptions I have come across. In mechanical scenarios, that is priceless. I'm sure a turntable guru will see it and go, "aw. I know what that is". Good Luck.

I HAVE A 1951 AMI D-80 JUKEBOX,THE TURNTABLE IS JAMMED.


There are two motors with beige/tan plastic covers over them, one on turn table platter and the other on the record changer mechanism table. Take the cover off the one on the turntable and spin the motor by hand. Depending on how you spin it the arm will either go back up or down

My stanton t50 turntable plays too fast even when the pitch fader is at the slowest speed


You need to calibrate your pitch control. This requires a small precision screwdriver (similar to something you would repair eye glasses with). If you look under the turntable where the pitch control is you will find 2 small holes, 1 marked 33 and 1 marked 45. Turn the turntable on and set the pitch control lever to zero pitch. While the turntable is spinning insert the screw driver into the pitch calibration hole under the turntable and twist the potentiometer back and forth until the turntable pitch is zero (I believe clockwise is faster, counterclockwise is slower as you look up from the bottom of the turntable). This is a fine tune adjustment and will not require much turning to adjust the speed (1 or 2 mm's) either way should start to bring you into zero pitch. The platter speed can be verified by the little dots on the rim of the platter. They should appear stationary in strobe light on the power switch when you are at zero pitch. When you are adjusting the speed you will observe the dots on the platter rim spinning clockwise and then counterclockwise as you adjust the fine tuning. Fine tune the speed until the dots appear stationary and you will be back to zero pitch. You have to adjust the turntable at both speeds 33 and 45 using the correct fine tuning hole under the turntable. My personal experience is it is easiest to do this with 2 people. 1 person to hold the turntable level and running, while the other adjusts the fine tuning. Hope this helps.

Braking not working right


Well, does the platter spin at a constant speed (33 or 45 rpm), or does it spin super fast? If it spins at a constant speed, and it just wont stop, replacing that pot should do the trick (VR201 can be purchased HERE). You can attempt to replace it yourself (soldering skills are required), or just buy the part, and have a service tech replace it for you.

If it does not solve the problem, then the issue is with one of the IC's (integrated circuits). This is a more complex diagnosis and repair. But try replacing VR201 first, then taking it from there.

Good luck!
