Rittenhouse Service & Repair Forum
I have a Rittenhouse intercom system that was installed in the 60\'s that worked fine until recently. Everything still works fine except the main intercom/control unit. Is there a replacement unit I can buy that I can use with all my existing speakers, etc throughout the house? Even a unit that only played music would be OK with me.
