Crosley Pup

from Wikipedia, the free encyclopedia

Crosley Pup was short for Crosley Puppie and was the name of a mass-produced and therefore comparatively cheap medium-wave radio set for headphone operation that could receive stations within a radius of about 15 miles. It was introduced in 1925 by the "Henry Ford of the radio" Powel Crosley Jr. , whose Crosley Radio Corporation in Cincinnati , Ohio produced the apparatus.

In terms of circuitry, these were to a feedback Einröhren- Audion for battery operation with the 1923 from the Westinghouse Electric Corporation produced directly heated tube WD 12, which got along with an anode voltage of 22.5 volts and a heating voltage of 1.5 volts.

With a retail price of $ 9.75 compared to more than a hundred dollars for other makes, it helped the company, combined with clever advertising in which the popular dog figure Bonzo played an important role, to sell this device in large parts of the American population.
