This unit is NOT belt driven. It is direct drive, meaning, that a series of Integrated Circuits (IC's), and various other electronic components control it's speed. If it's going very fast, more than likely one of the IC's (or multiple), have gone bad. You need to take this to a service center for repair.

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!

When i press Start/Stop button, the platter is not moving/spinning. THe ON/OFF light is working, same as the pitch light and the lamp...


The chances are the rubber drive belt has either broken or stretched so that it has fallen off the drive pulleys.
You will need to gain access to the underside of the turntable to replace it.
With most turntables the process will be to secure the tone arm (a rubber band will do the trick) before turning the whole thing upside down and unscrewing the base.
Replacement drive belts are easily available on the internet. Search by make and model number of your turntable

One of my technics' 1200 turntable's tone gets too high


You can try adjusting the pitch's gain, which is located on the pitch control circuit board. Only problem is that you'll have to take apart your turntable in order to get to that section (its on the bottom).

If that does not work, your pitch might be bad, or one of the main circuit drive IC's might be bad.

Hope this helps some.

Help for technics 1200 MK2 and 1210 Speed is too fast


On the 1200MK2 the pitch control slider is for just that purpose. Disregard the 0 setting and use the illuminated strobe marks on the platter to adjust to nominal speed. When they appear to be motionless you are there. The control on the 1210 may be a knob but the same principles apply.

EVERYTIME I PLAY A RECORD IT DRAGS TO PICK UP SPEED


Are you sure you have a Technics SL1200MK2 Direct Drive Turntable? If so, then there is a major problem with the drive system. This can only be diagnosed and repaired by a qualified technician.

If your turntable is not the Techics SL1200MK2, and you have no idea what turntable you have, look at the model's label, if it says BELT DRIVE - this is the reason why it drags to pick up speed. If it says DIRECT DRIVE, then take it to a service center for repair.

Tonearm lift is probably a deteriorated belt. Google it, it's pretty common. The platter spinning might be due to a bad control board. You'll probably have to go to a repair shop to diagnose it.

Sounds like you need a new pitch control. YOu can purchase a pitch control separately and install yourself, however soldering is required. You will have to solder off the old board, and solder on the new board.

You can purchase the PART HERE

Technics sl-1610 mk 2 turntable


Unfortunately, it does sound like a drive issue. Just so you know, these units are direct drive, so there is no physical motor. It's just a bunch of various circuits which drive the unit, and if any one of them go bad, it will affect your turntable speed. You will need to have this looked at by a service technician to determine which circuit is faulty.
