Rittenhouse Service & Repair Forum

I recently moved into a house that has the Rittenhouse All Transistor RCM-1 system in every room. It\'s obvious this system has not worked in a few years, but I want to repair it and keep it with the time of the home. A newer system would take away from it\'s appeal. Is there anyone in the Tulsa, OK area that could help me?Thank you,Candy Cicoria

I purchased this residential unit in 1986. It is now giving a significant hum and does not produce all of its chimes.Does this give you a clue as to repairability?

Need new springs for the hammers. This is an old door bell and it has lasted about 40 years. The new ones are sick. This is the best I have heard and would like to keep it another 40 years.
