The TT-5 was RCA's least expensive set in 1939. It is a vision-only set, requiring an external radio to receive the sound. It has a 5 channel tuner and a 5 inch screen. The cabinet and chassis are in excellent condition.
We have learned something of the history of this set. It was purchased by an engineer in Princeton, New Jersey. In 1968 he "restored" it for the 1968 25th anniversary of the Sarnoff Research Labs. Unfortunately, his restoration involved substantial modification of the original circuits After his death, the set was sold to a collector.
This is a photo of the RCA assembly line, showing the TT-5 being built, taken for the 1939 book Magic Dials, which described RCA's introduction of television.
