Rittenhouse Service & Repair Forum
I have a rittenhouse westminister door chime master model 631 and 632 that I removed from my family home when it was being sold. I have everything except the Rittenhouse no. 42 transformer, which is need before the electrician can install it in my home. Do you have this transformer or know where I can get one? I appreciate your help.

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…Purchase or Repair:
