The break potentiometer is probably bad and will need to be replaced. This is located underneath your turntable platter, on the main circuit board, and it's labeled BRAKE - VR201 - you can purchase a replacement part by clicking HERE

Not the easiest fix, as it does require soldering skills. But if you have that down, then this should be easy for you.

How do I fix the speed of my Technics SL-6 Turntable?


Something has gone awry in the world beneath the platter so you will have to remove the platter to expose the mechanism, then observe what happens (or doesn't happen) when the buttons are pressed.

I have a Zenith Allegro Console with a turn table and it spins to fast. Are there any adjustments I can make?


It depends what kind of drive this model has. It's possible that since this is a model that has the 78rpm speed it could use the old type of drive. If so then what happens is that a mains powered motor has a three position pole on it. A rubber tyre presses on each section on the pole. The speed switch manually moves it up or down. The tyre presses on the motor and on the rim of the platter. A worn tyre or one that is not moving to the right section on the motor will cause incorrect speed.
The only other form of drive would be a belt, but not many belt drive turntables were built with the 78 speed of this date.

Turntable spinning to fast


Clearly an electrical fault. Could be something to do with the power supply or the speed control circuit, or even the motor itself.

Direct drive spinning to fast


Sounds like a speed sensor in the motor has opened up. You need a repair shop my friend.

Counter clock spinning


pitch slider can cause an unstable motor (clean with can of air and switch cleaner) if it spins counter clockwise it will be the brake. there is a little screw in a hole under the platter to ajust the brake speed.

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.

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!

Technics 30th Aniv Edition - help with break speed.


Do you recall the adjustment you made? That brake switch under the hod is real sensitive. For starters, try pulling back half way from which you adjusted, to get a sense of sensitivity. Did you alter the pitch switch at all?


Keep me posted.
