My house has a roomy foyer with cathedral ceilings and was built about 28 years ago. When we started thinking about a door bell, we wanted something that would benefit the space and was audible throughout the house. My wife is somewhat hearing challenged, so we kept that in mind while we looked for something. We settled on a NuTone~(TM) chime with four large brass tubular bells, which was presented to us by my parents. It filled all the requirements and more, especially since the sustained melody removed any auditory uncertainty (Did I hear the bell???). Now, 28 years later, the chime has died and needs replacement. Because of the sentimental value attached to the chime, I started looking at repair options. The bells are struck by four electric solenoids sequenced by a motorized (mechanical) switch mechanism (Figure 1). Unfortunately, the motor was dead (Figure 2).
