Troubleshooting Rittenhouse: Common problems and repair info

Rittenhouse All Transistor RCM-1

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

Buying a condo with an inoperative Rittenhouse Model 7021 intercom system. Was constructed in late 70s. Is the technology so out of date that it is not worth restoring? Should I consider restoring the unit, about how much am I looking at? Is there a dealer here in AR, or do I have to ship it to you …Purchase or Repair:
