Hi, The pitch on my Technics SL 1200 MK2 has started playing up for the first time. I bought the turntable second hand from a shop that specializes in Technics turntables two years ago. Here's a video of the problem https://photos.app.goo.gl/bKn4vSbPmvi5AZqk6 When I start going into the +, the pitch starts to become unstable. It seems fine in the - although I've noticed that beatmatching has become a bit harder that it used to be so it might also be a bit unstable but not very noticeable. I've checked some similar threads on forums but the answers are a bit all over the place and I'm not sure if my problem is exactly the same or not... The shop I bought them at said without having seen them that it sounds like an IC related problem and quoted me 85 euros for material and installation. I'd ideally like to try and do this myself as I'm strapped for cash at the moment, so I'd really appreciate some advice. Thank you
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

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
Saludos Franco Dosil

It sounds like the pitch slider needs to be replaced...

need to know if it powers up. Does it try to spin, do you hear it trying to spin? More than likely the on/off switch went bad. No, I am not referring to the ON/OFF knob. THere is a switch this engages when turned. The part is S601. You might also want to replace the Start/Stop switch as well. If neither work, then the issue is on the main PC board, and probably IC101, or IC201 with the problem. At this stage, you will have to have a service tech look at your unit.

Check that your voltage settings are set correctly. This is located
underneath your turntable platter. If you remove the slipmat, you will
see 2 holes on the metal platter. Rotate the platter till you see the
voltage switch, located @ the 9'o'clock position. Make sure it's set to
your correct settings (N.America = 115V / Euro = 220V). If not, you
will need a flat head screw driver to switch it. Before you switch it,
make sure your unit is off and unplugged. After you swich it, it should
be ok.
If your still having issues with the speed and the pop-up
light, then there is something seriously wrong, and will need to be
checked by a technician. Sometimes a resistor or IC will go bad,
causing the speed issue, but for the pop-up light - that's usually
faulty wiring generally caused by an incorrect replacement.
Did you buy this new or used? Have you had this serviced recently?

check the antiskating. then i don't know.. maybe the tonearm has to be calibrate
SOURCE: technics turntable plays but no sound with Sherwood receiver
The problem is the fact that the new receiver has no phono input. The phono input has an extra stage of amplification built in. Your receiver is working fine. You need to purchase a phono pre-amp. These run around $20. Connect the turntable to the preamp and the presmp output to any line level input on your new receiver and everything will work as expected.
