This is correct. You can use more bells too. Solutions always
exist.

~~~ A better image is that the resonators act as elements that
transport a "wave" from the input capacitor to the output capacitance.
The wave may have to move back and forth several times before
reaching the maximum amplitude at the output.

These are more like CW systems, electronic CW oscillators.

Surely possible, but not very clear how... Yet.
