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
