rajung, if I understand you correctly the problem is not the coil but yet the position/distance of the switch and tip of the PB skirt. I would try to adjust the switch so it takes less movement of the skirt to activiate the PB coil, but not too close or else the coil will fire when other things on the playfield "activate" sending a vibration through the playfield. Did you work on the PB and if so you did put the right springs back between the skirt and body right? Just some food for thought, good luck.

You need to adjust the switches and check the spoons for wear and cleanliness. Also check the skirts and the finger that goes down and fits into the spoon. DE pops will trigger just as easily as any other manufacturer if they are adjusted correctly.

I bought wms spoons and changed the de ones out.
Helped alot...they seem to pop more often..they are not as stiff as the de ones.

Rajung I noticed my Tommy does the very same thing. I have only had the machine for 6 weeks or so now and haven’t checked the adjustments on the pop bumpers yet. I will say for sure they are not sensitive enough and like all pop bumpers they can be tuned and adjusted as mentioned above!

My pops are the same. They are not nearly as lively as any of my B/W games. The layout certainly doesn't help. If anything, this is the most glaring design flaw in the game. Often, the ball will just dribble right through the pops without even touching any of them.
