DIY: How to get 110VDC from AC
Another possibility is below with a small 10:1 transformer used as a stepup transformer.  Choose cap RC time constant near 20ms for each half cycle or 25Hz, which is common for Europe. Then tune to get resonant frequency of spring toggle bell for max volume.  This is fairly low current and turns ratio can be adapted to other supply voltages. EST. 1W max.
