Olympic RTU-3H Duplicator

Many of these sets could be connected to a “master” TV receiver, allowing. Similar sets were used in the Hotelvision TV system. It has no tuner, and has audio and video inputs. Similar units were used as part of the Hotelvision system. A series of pushbuttons on the duplicator sent a signal back over a cable to a central point, where TV sets with audio and video outputs were permanently tuned to the channels available in the area. The signals from the pushbuttons routed the A/V signals from the desired channel to the duplicator, located in a hotel room. A separate cable went from each room to the central point.

This set was refinished by and donated by Charles Harper of Paris, KY.

Tom Scarpelli noticed that his Olympic mirror in lid set had a jack on the back for connecting a duplicator and sent us these photos:
