This video contains some Chrysler dealership promotional film clips, on introduction of some of its NEW Standard and Optional equipment, that became available in the fall of 1955, for its NEW line of 1956 Chrysler and Imperial car models.

Chrysler and Philco had developed and produced the "World's First All-Transistor car radio in 1955". This "Breaking News" was first announced in the April 28th 1955 Wall Street Journal newspaper. Chrysler had made this All-Transistor car radio Mopar model 914HR available as an "Option" in the fall time of 1955, for it NEW line of 1956 Chrylser and Imperial model cars. Chrysler had used the Mopar model 914HR, which was also Philco's model C-5690. Philco had originally re-designed the Mopar model 912HR, which was a 5-push button "Town and Country" AM radio, with an electronic signal-search touch bar tuning and contained 9 vacuum tubes inside. Philco decided to use this "exact" same radio and re-design the inside circuitry with (11) transistors and NO vacuum tubes, making it the Chrysler Mopar 914HR or Philco C-5690 All-Transistor car radio model. And if the customer had ordered Chryler's "optional" Highway Hi-Fi in-car record player, then Philco had added an extra transistor in its circuitry, which was used as an phono pre-amplifier (2N43), and making it a total of (12) transistors inside. This car radio's circuitry also included the "famous" Philco Surface Barrier Transistors, which were the World's First high-speed high-frequency transistors that were developed in 1953 by Philco, and could be designed for computer usage.

A "Rare" look at the radio's chassis, which shows all of its transistors and locations, is shown near the end of the video film.

This "Rare" highly engineered All-Transistor car radio, was short lived and by the end of 1956, Chrysler had discontinued this car radio model. Chrysler had decided that it would no longer make All-Transistors car radios available for its car models, during the rest of the 1950's. And Chrysler instead decided to use "Hybrid" car radios, which contained BOTH transistors and vacuum tubes inside.
