Sound to me Gav that the selector unit is not pushing out the right pins its very hard to see but try adjusting the arm with the coils that push the pins
Was worth checking out..... i chose E7.. allowed the juke to fire the pin and then disabled the scan with the controller. Removed the scan assembly and looked at the back to see which pin had been pushed through... sure enough.. was E7.
So its hitting the right pin.
Mate, checking in the manual, the whole record magazine is held on the spindle by 1 allen screw ( hard to believe but its all there in glorious black and white). Seeing as ive already reset the whole assembly and yet its still 2 spaces out, my theory now is that the magazine is not at zero point on the spindle.
Ill try get some time over the weekend... it means pulling the whole guts out again ( groan), but ive braved it once already... it aint so scarey after all
