Rittenhouse Service & Repair Forum

I am looking for a wiring diagram for a Rittenhouse, Spartan Electric, Fayettevile NC C8845 unit which is 30 to 35 years old. It seems to be either able to use two D cells or 16V transformer but I am got sure how to wire it up. Any ideas? Thanks.

I bought a house built in 1950 with an old Rittenhouse door chime, Model #365. I have no idea if it can be repaired. I don\'t have the front door button. The inner workings are very dirty. Do you think it\'s worth sending to you? Thanks, Kathie
