Ya Al & Jerry,On this unit it's IC703=BA5936A,which I replaced.I have the
necessary drive voltage from the ic to the sled & spindal motors but have
equal volts on both pins of each motor.What I can't figure out is where the
ground comes from to enable the motors..Tks for your
i/p...............Don....
