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.
