Correct up-kicker coil for Black Hole and Haunted House
The lower-to-upper playfield up-kicker on both games takes coil A-4893, wound with 535 turns of 22 gauge wire; some manuals print the wrong number. A Williams 22-550 can stand in, but it is a poor fit in the Gottlieb coil bracket. Make sure the coil has a diode with its band on the power lead.
