Pan Am Boeing 377 Stratocruiser Clipper Seven Seas - RF CafeMost aviation enthusiasts upon hearing the name Pan American "Clipper" thinks of the large four-engined amphibious airliner. There were other models of the Clipper, however, including the Douglas DC−4, the Lockheed L−049 Constellation, and the Boeing 377 Stratocruiser. The latter (Boeing 377) appear to be the early concept model depicted in this 1945 Raytheon vacuum tubes promotion in Radio−Craft magazine. Raytheon was a major supplier of electronic components, equipment, and systems for the military and government throughout World War II. Manufacturers came to trust and rely on the big-name companies for high quality and dependable components. By the time this advertisement appeared, Germany had recently signed an unconditional surrender, and Japan was only a few months away from total defeat. Sadly, many of the familiar names from the era have either been acquired by foreign firms (and usually renamed) or have gone out of business due to poor management decisions (usually from failing to keep up with changing times).

Raytheon Vacuum Tubes, June 1945 Radio-Craft - RF CafeRaytheon Tubes Chosen for Pan American's Postwar "Clipper"!

Feast your eyes on this mighty, 100-passenger airliner! When peace comes, a giant fleet of its sister ships will girdle the globe for Pan American World Airways. And in each of them will be the best electronic devices to come out of the war, equipped with famous Raytheon high-fidelity tubes!

Raytheon tubes have been used for years by Pan American, and it is because of their proven performance, fine reception and complete dependability that they were selected to play such a vital role in this great company's future operations. The assignment is but one of hundreds of postwar applications for which Raytheon tubes have been specified by America's radio and electronic industries.

When tubes are more readily available for civilian use, Raytheon will offer radio service dealers the finest tubes in its history ... tubes combining long prewar experience with out-standing wartime development. And that's not all. They'll be backed by a Raytheon merchandising program that will be the most beneficial ever offered you. Keep your eye on Raytheon ... for greater postwar profits!

Increased turnover and profits ... easier stock control ... better tubes at lower inventory cost ... these are benefits which you may enjoy as a result of the Raytheon standardized tube program, which is part of our continued planning for the future.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
