1200 mk2 users I need help

[CaseJones]

I was playing a gig last night and one of my decks started to speed up on its own with out me touching the pitch.I turned it off and turned it back on and it worked again for a few minutes than did it again.Has anyone ever had this problem?If so do you know how to fix it? Thanks for the help in advance

How much is it speeding up by?

At a guess I'd say it's a problem with either the pitch fader or IC301. As your other deck is working ok, try swapping the pitch PCBs to see if the problem moves. Or you could just replace the pitch PCB and see what happens, it never hurts to have a new fader plus a used one for a spare.
