Question about Philips gemini TT-01 Turntable

1 Answer

Speed Changes My turntable is not spinning at a constant speed. Its like theres something interfering with the spinning mechanism. At the fastest setting its still going too slow, and the speed varries on its own. You can hear it start to go slower and then speed up and go slow again. Any help would be very appreciated, thanks.

Re: Speed Changes

Perhaps it's time to change the belt on your unit. If after you change the belt, you still have the same issue, then the problem might be with the motor itself. The motor itself is a relatively inexpensive part, around $20-30, and the labor should run in the 40min range - so you can get an idea of what it will cost. Hopefully it's an easy fix. Not sure where you could source the belt, but if you take off the old one, you should be able to match it up easily. Also, there should be a part number in the user manual, and instructions on ordering a replacement belt or at least a part number. FYI, belts generally run in the $5-15 range, and are user replaceable. Good Luck!

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.

Constant speed

It needs to be taken apart. The bottom needs to be removed. Not an easy job if you are not mechanically inclined. There are pots inside that need to be sprayed with contact cleaner. Pots are under the knobs that control the speed. They have holes on the sides of them. You can purchase cleaner at a radio shack or electronic parts store or online.

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.
For the manual visit the Gemini website.

Turntable spins to fast.on 33 sounds like its on 45 but on 45 its even faster

Possible that the motor is working with a different speed. It can be fault in the drive, fault in the mechanism.
What is required is the need to remove the TOP plate and look to see the drive of the motor. If there is slipping of the drive it can result in higher speed. If so it can be aligned and corrected.

Our Technics SL-1200MK2 has issues with the direct drive. It does not spin at a constant speed. When stopped, it does not stop immediately. What can be done to solve this?

To adjust stopping speed you'll have to remove the plate by pulling it up. Then there is a plastic cover that has some screws, remove the screws and remove the plastic cover, you'll find a variable resistor that reads something like brake. Adjust it to the left or to the right with a screwdriver and see at which position works best.
To solve the constant speed problem you'll have to replace the pitch regulator.
Go to any panasonic/technics service and buy the pitch. If you have a bit of soldering skills you'll be able to replace it by yourself. You can access the pitch regulator unscrewing all the screws under the device and then removing the cover.
Hope you can solve the problem!

My Crosley turntable is spinning too fast at 33RPM

Mismatch speeds on older turntables is normally due to either 1) a kink in the speed switch mechanism or 2) a hardening and slipping of the rubber drive wheel.
A very small motor with a chamfered shaft drives the rubber drive wheel, and the wheel is moved by the speed control up and down the drive shaft to produce various rpm speeds.
In your case, it's likely turning at 45rpm because it isn't settling onto the 33rpm part of the shaft.
Piddle with the speed control, then count the speed (number of turns in a minute) You'll figure it out!

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!
