Thats my experience too. Change the motor for an 8 wire 960inch, and I 
can now move that g0704's head at 140 ipm, either direction. And do it 
20 db quieter than the 860 drive could do it. That A. D. line powered 
drive is amazing. But it sticks out of the front of the box around 2", 
precluding ever putting the lid back on it.
