Series FL23/600-30/2600 vs parallel FL11630 flipper coils
High Speed through Millionaire use the series wound FL23/600-30/2600: the middle lug is common, there is one diode across the outer lugs, no EOS capacitor, and the EOS contacts pit from the back spike. From F-14 Tomcat, the parallel wound FL11630 has an outer lug as common, needs two diodes, and takes a 2.2 mfd 250 V EOS capacitor; opening the EOS drops the power winding out of the circuit.
