Rittenhouse Service & Repair Forum
Hello! Do you have any parts for Rittenhouse (Emerson) All Transistor Radio-Intercom System, Model RM-1 (AM radio) or RM-2 (AM/FM radio)? Our system dates from the 1960\'s--still going strong. But I need knobs and especially the instruction manual because I don\'t know how to answer and use the exterior Door station (or for visitors to talk to me). Maybe a manual for another vintage Rittenhouse model would have useful instructions? Any help would be appreciated. Thanks, Diane Reichard in Princeton, NJ ~~ dpreichard@att.net

The small piston that strikes the chime does not return back to the original position. There is a spring on the piston. It seems like the piston should have a retainer of some sort on the end to hold the spring in place. Is there supposed to be a retainer on the end of the piston to keep the spring …Purchase or Repair:
