I recently picked up a solid state E.K. and three of the four chimes seem weak. I put new foam strips underneath the chime plungers to give them an extra boost, but with no improvement. I was going to order a PBR chime rebuild kit even though everything looked clean and fine, and then I noticed that the three weaker chimes all had replacement coils, while the one strong chime had an original coil. The replacement coils have the right number, but I've got to believe they are somehow weaker or perhaps installed wrong. Anyone else experience this before. I seem to come across weak chimes in Bally games fairly often and almost never on Gottlieb's of the same era.

In this case, mine are perfect. And putting felt underneath to lift them an extra quarter inch didn't help. I ran a jumper from the weak coil to the strong coil and then activated the strong coil by hitting a target that would normally activate the weak coil and the strong coil activated fine, so it is not a weak impulse. It just seems to be weak coils even though they are supposedly the correct number.
