Let me give another application of this... Early Dataeast games *love* to smoke the left lane kick back coil. The original is an 23-800 coil, and the pulse driving that coil is too long. The TIP driving transistor loves to bake, and the coil locks on, and burns. I go tired of replacing the coil/transistor on our Time Machine for example. So after a TIP replacement (which burned and shorted), i changed the coil to a 26-1200 (14 ohms). That's significantly less current draw, and i haven't had to deal with a burned coil since. Is the kick back less powerful? Yes it is. But it's still powerful enough to do it's job.
So the 27-1500 might be a little weak but could be worth a shot. I personally wouldn't do it, although they claim going up won't harm things at the risk of the feature not working (vs going down and burning the board).
