After some experimenting I found my two identical bells worked best in

some bells are fine in series, some wont work at all.


I'd *guess* the types that don't work in series are universal types that
can be powered from AC or DC - these use a mechanical switching circuit to
make the hammer vibrate. AC only ones simply follow the waveform. And most
bare bells you'd buy today will be AC only.
