The chime unit uses a hybrid design that will fit into almost any Williams electromechanical pinball machine.
Convenient screw crimp connectors allow for easy solder free plug and play installation.
The overall chime housing and brackets are made of tough 18 gauge (1 mm thick) galvanized steel which insures years of service even with extensive home use.
Although the chime unit does not have the traditional amplification box, the unit uses slightly more powerful coils to produce up to 95 decibels of pleasing chime tones, the same amount of volume produced by chime units with traditional amplification boxes.
Mounting screws and step by step illustrated instructions are included.
