Stronger flipper coils for Gottlieb EMs
Williams and Bally EM flipper coils are stronger than Gottlieb ones, so a Williams coil can add kick to a Gottlieb game. Williams coils are 1/32 to 1/16 in longer and may not fit the Gottlieb bracket. Match the voltage: Gottlieb flipper circuits are usually about 26 V; some Williams and Bally coils are for 26-30 V but others for about 50 V, which will be weak on a 26 V circuit.
