Technics 1200 MK2 displaying irregular speed to include dragging and slowing

First, I'm not a Technics tech.
* Normally I would suggest to check for warranty, but this unit is outdated.
* Try to contact ; https://www.technics.com/us/support/
*** The following is for information only.***
* The following vid shows the speed switch on the left. If it's not tracking then there may be a problem in the selector switch, sync tracking, or motor drive.
* You may want to check the "window" or sensor of the the speed sync light (the orange light). Wipe down the lamp and the peep hole where the sensor is located (on or near the lamp)
* Wipe down the outer edge of the turn table to clean the metal "dots" or "bars" on the rim. This is what the sensor reads to determine speed.
* Speed controls and direct drive turntable are not customer serviced parts (other than replacement of the component).

Try plugging it into a different power point. The problem is with the power supply fluctuating. You can eliminate that with a UPS, here is a link to wiki http://en.wikipedia.org/wiki/Uninterruptible_power_supply

Hi, What do you mean by this pls, you need a new top or how do you fix a broken one?

Thanks Mark H (superstar DJ)

Yes and the good news is the 2SD1265 will cost you under a few pounds including P&P from Grandata Limited.

Most likley just the bulb itself. There is a guide on how to change the bulb on my website :-http://www.technicsdjuk.com/repair
The bulb is avaialble here :- http://cgi.ebay.co.uk/TECHNICS-TARGET-LAMP-SL1200-SL1210-GENUINE-NEW-PART-/300442165558?cmd=ViewItem&pt=UK_AudioTVElectronics_HomeAudioHiFi_Turntables&hash=item45f3bfa136

Most likley the pitch fader has worn / become faulty.
Look here for a new one :-

Usually just the knob, look here :-

Since this is a direct-drive turntable, it isn't a slipping or stretched belt. You will need a technician with a couple pieces of equipment and some experience/training to find the source of the problem. I suspect the part(s) will be the minor cost of the repair.

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.

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.
