Hi Thomas, as you say, it's not the engine, nor the integrated engine
Most likely, the pitchel potentiometer that generates the problem
I would try to clean it, applying a small amount of contact cleaner and test if there are improvements
Keep in mind that it is the Pitch potentiometer that is changing the speed
Comment if the suggestion served
Regards Franco Dosil
Hola Thomas, por lo que comentas, no es el motor, ni el integrado del motor
Lo mas seguro es que el potenciometro de pitch el que genera el problema
Yo intentar?a limpiarlo, aplic?ndole una peque?a cantidad de limpiador de contactos y probar?a si hay mejoras
Ten en cuenta que es el potenciometro de Pitch el que va modificando la velocidad
Comenta si sirvi? la sugerencia

Check for bad solderings on Q201 and surrounding areas.
Resolder IC101 and IC201. If that doesn't help, Q2 and Q3, both 2SD637R, could be broken. If that doesn't fix it replace the electrolytic capacitors. Cheers john. Styluscity
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
The pitch pots have been altered. there located under the platter & cover on the main circuit board.it's a peace of **** to sort them. if you help e-mail me [email protected]
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.
The reset button disables your pitch control and allows the turntable to rotate at TRUE "0" (zero). FYI, these turntables were NOT made for DJing. They were made for radio, studio, and high end home use. They became DJ turntables, because they were perfectly built for the trade. So, the pitch reset button is more of a function best suited for radio stations or a producer who needs to record or play at a true zero speed.
Now, on to your question...
More than likely you just have to calibrate your pitch control. There are various videos on YouTube on how to do this properly. Just do a search CALIBRATING 1200s or similar. FYI, all the Technics SL1200/1210 MK series are the same inside. MK2, MK3, MK5 - so don't worry if you only find videos on calibrating MK2's or MK5s - works the same on all the models.
