Daven Television Receiver

In 1926, Daven introduced its resistance coupled amplifier, designed for high quality radio receivers. Because it used capacitive coupling, the frequency limitation of transformers was eliminated, allowing the full audio bandwidth to pass. This characteristic was important for television in order to get the maximum possible detail in the picture. 

With the introduction of television in 1928, Daven began to market their amplifier for TV use.

 

Daven sold receiver kits and factory assembled sets. Our receiver looks professionally made, but could have been home made by a person with electronics experience. The following chapter, from a booklet from the Trade Catalog Collection of the Henry Ford Museum in Dearborn, Michigan, describes a receiver very similar to ours. The booklet was published in 1926, so this receiver was designed for radio reception. It gives instructions for home construction.

Our receiver is very similar, but has a contrast control at the point that the neon tube was connected.
