Yeah two balls are coming down at once from the RHS ramp when the pin drops.
OK..
1stly check correct coil - should be AE-26-1200.
2nd - check actual assembly is secured to underside of playfield (ie not loose).
3rd - most likely the coil sleeve is dirty / worn. Not sure if you've seen one before. Its a consumable part of the coils and need changing every so often. I would advise to replace rather than clean.
They are only about $1.00 or so.
The part number is 03-7066-3. Either RTBB or Mark should have them.
