Of course, to get the original manufacturer part you will pay a little more, but there are many after market parts that will do the job for less money. These belts are widely available and not expensive. For the belt to get in the wrong position to begin with, it would have to be stretched too far which means it needs to be replaced. You may be thinking “why would I replace the belt if it is just in the wrong position? Can’t I just move it?” No matter which of these 2 problems your turntable has, the solution is the same. Belt is in the wrong position (rides up on the spindle too far).There are 2 typical problems with the belt that will cause your speed to be off. Over time it can stretch out or get repositioned, causing speed deviations in the playback. The turntable belt is like other belts you may have seen on vacuum cleaner motors or other small electronics like cassette players. Just spray a small amount of the product into the switch while gently moving it back and forth. You will need to get a bottle of electronics cleaner like Deoxit. Cleaning and lubing the switch is much easier and will only take a couple of minutes. You would have to have a shop do it or do it yourself.Įither way you are paying for the part and labor. Replacing the switch is the better solution for the long term but will cost more and take more time. If you hear the record slow down or speed up slightly, there is a good chance the switch could be the issue. To determine if it is the switch try gently moving it slightly while the platter is spinning. This is often caused by dirt or grime inside the switch that can build up over time. This will send too much voltage to the motor which causes the record to spin too fast. Sometimes the speed switch can have an internal issues where the switch is slightly too far in one direction or the other. There are about 4 main reasons a belt drive deck could be spinning too fast, and 4 different fixes. In other words: the solution depends on the problem. How you fix it depends on why it is too fast. Once you know for sure that the turntable is spinning too fast, continue with the rest of this guide. There are other apps as well but those are the most popular and according to the reviews, they are the most accurate. There are 2 popular apps that get good reviews for this purpose, RPM- Turntable Speed Accuracy and RPM Speed & Wow. Luckily, there are apps you can put on your smartphone that can check the RPMs of your platter. Most likely you will not have access to that kind of equipment. In a stereo shop they can measure your RPM by using a strobe and calibrate it that way. 3 Record Player Playing Too Fast: Final Thoughts.1 Is My Record Player Playing Too Fast?.The turntable is initially spinning clockwise when looked down on from above at a constant frequency f0. A turntable is a uniform disc of mass m and radius R.What was the magnitude of the dryer's angular deceleration? A student opens its door and it comes to rest after rotating through four revolutions. A clothes dryer is spinning at 75 rpm.(b) If safety regulations require that the blade be stoppable within 3.0 s, what minimum angular acceleration will (a) Calculate the linear speed of the tip of the blade. Consider a 59-cm-long lawn mower blade rotating about its center at 2990 rpm.THe turntable very slowly speeds up to 60 rpm. THe coin has static and kinetic coefficients of friction with the turntable surface of us=.8 and uk=.5. A 5.0 g coin is placed 15 cm from the center of the turntable.(i)What is the average angular acceleration of the centrifuge? (2%) (ii)What is the distance that a (b)A centrifuge has a maximum rotation rate of 10,000 rpm and can be stopped in 4 seconds.The turntable starts from rest at t = 0 and rotates with a constant angular acceleration of 0.630 rad/s2. The coefficient of static friction between the coin and turntable surface is 0.390. A coin rests 15.0 cm from the center of a turntable.(a) What is their angular speed in rad/s? (b) If the doll is 13 cm from the She places one of them on an old record player turntable and sets the angular speed at 33.3 rpm. Grace is playing with her dolls and decides to give themĪ ride on a merry-go-round.What is the turntable's angular velocity, in rpm, just after this Two 550 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick. A 1.5 kg, 20-cm-diameter turntable rotates at 110 rpm on frictionless bearings.A childe of mass 40.0 kg, initually staning at the center of the turntable, runs out along a The moment of inertia of the turntable about this axis is 1200 kg * mg^2. A large turntable rotates about a fixed vertical axis, making one revolution in 6.00 s.
