Hello. I found a very old telephonic bell, all the internal components were stolen except for the electromagnets. I made it work using a function generator from my school and it works perfect with 20HZ or less AC, with more frecuency it stucks in one position without ringing. I didn't found any information about the kind of circuit that I need, someone has an idea about how to achieve this low frecuency?
