Ok, had a piss about with the pitch pot and couldn't get it sorted. Pain in the arse.
So time for the Q lock removal. After reading every page and tidbit google had to offer I settled upon this site which explained exactly what I was suffering and what I could do.

Absolute doddle to do:

Take platter and internal cover off, then unplug the group of wires on the right of the PCB



Snip the orange wire and tape it up, leave a bit of length either side of the snip incase you want to put it back to normal. You can also snip the yellow wire to lose the LED but everyone likes LED's, right?



To take it even further and completely eliminate the quartz precision you need to make a snip on this resistor. But little point in owning technics if the precision isn't there imo.



You would also need to get rid of the ball bearing in the pitch slider to make the slider completely smooth but bollocks to that. Knowing where dead center is (after tweaking the pitch pot and setting it up right) is useful if you want to rip some vinyl or just listen to some tracks.

All in all I'm happy now :)
