Done that (well, similar...), results attached. The cap(s), wherever it is (they are), part-resonates the bell(s) and govern the current drawn, so forming part of the REN.
This is quite complicated, but I have an idea about, instead of that series resistor, just producing heat, a capacitor of e.g 1 F will do the job, but not use any effect. If we dont use the effect for heating, it may be used for ringing.
If someone with skills could please calculate the effects there of, I would be happy.
