Default Technics 1220 mk2 pitch control problem

I have a problem with the pitch control on one of turntables. According to Serato, when I try to pitch it .5% down, it decreases 2% percent instead. And when I try to pitch it up 8%, it increases only 7.5%. I restarted serato and my laptop and the same problem keeps happening. Basically, I'm having trouble beatmatching since the pitch automatically jumps from 0% to 2% even if I decrease the pitch slightly. HELP!!!

Good chance the fader is end of life.
Replace it and if you have a frequency counter, adjust VR301 for 262.08 kHz and, with an ohm meter, VR302 for 2.7k ohm.

Schematic can be found at various places on the net. Audiokarma is one of them.

Oops, that would be vinylengine.com instead of Audiokarma.
