Rittenhouse Service & Repair Forum

We have an older intercom system M9325 stations, M9318, and M9322. We are wondering if there is anything we can do to reduce the standing hum.Thanks

I have the above mentioned door chime (Rittenhouse door chime model C8536) that does not work correctly. There where some broken wires from the transformer coils that I soldered back on and now it does not work correctly. Do you have a schematic for this unit?

I have the above model doorbell and really like the sound vs. the new \"electronic sound\" doorbells. Problem is the mechanism inside the doorbell (the part with the two knockers that the wires attach that hit the bells to make the sound) no longer works. Can I still get this part replaced and if so…Purchase or Repair: Ticket Image...

It seems like the piston should have a retainer of some sort on the end to hold the spring in place. Is there supposed to be a retainer on the end of the piston to keep the spring …Purchase or Repair: Ticket Image...
