  • The catalog 1930 for season 1929/30 names this 8 tube chassis "Lafayette Challenger Screen-Grid". It features 3 screen grid tubes 224, 2 tubes 245 for push-pull and a Utah dynamic speaker. "Wholesale Radio Cervice Co. Inc." writes: "Super-Efficient Circuit --- Lafayette-Designed", going on with: "In our research laboratories, where we have available every conceivable type of testing apparatus, Lafayette engineers have developed this amazing new receiver. It is a distinctly new circuit design that gives the Challenger a tremendous advantage over all other receivers that may appear to be the same.". Two knobs, illuminated drum scale. As illustrated on page 5 to 10 and inside cover page, the same chassis is used for Challenger 40, 18, 30, 10, 85 and 20.

    The list price for the chassis incl. speaker is $ 99.50 without tubes/aerial equipment or $ 128.50 with - but Lafayette puts a price of $ 48.50 or $ 62.71 all inclusive. See details and summaries for the models of this catalog.
