A SFL-24-600/30-2600 coil replacement will NOT make your flipper stronger. I just put a new one in from Marcos. It has an orange wrapper instead of white. It seems way weaker. Brand new EOS and lane change switch also. It just don't have the same snap as the old coil. Same voltage though. It is a trip. I went ahead and picked up a NOS coil from an old Comet to see if it is stronger. The Marco coil will make the Corkscrew but you have to hit it perfectly as to where the old coil was way easier.
