Notes The catalog 1930 for season 1929/30 names this 9 tube TRF chassis a "Screen-Grid Neutrodyne Neutrodyne-Beers Double Primary". The Lafayette Duo-Symphonic Screen-Grid has a "special Utah Stadium Dynamic-Speaker chassis" producing from 30 to 5000 cycles, linear power detection and local distance switch. Push-pull operation. The same chassis is used for Lafayette Duo-Symphonic models 342, 316, 324, 370, 343, 300, 362, 357, 325, 329, 350 and 352, a Phono-Radio Combination.

The Lafayette Duo Symphonic is in fact using the Wells-Gardner & Co chassis model C or CG, first type. You see this clearly by comparing the Rider's schematic Wells-Gard. page 1-1 and 1-2 (see versions) with the schematic "Wholesale" page 1-2. It is the "Old Type" schematic.

Nevertheless, Lafayette describes this the following way: "The problems of our engineers was not only to build a receiver that would outperform anything in the world, but to build the dame receiver at a price that would bring it within reach of the average home."

The list price for the model 343 Duo-Symphonic is $ 194.50 without tubes/aerial equipment or $ 219.25 with - but Lafayette puts a price of $ 95.55 or $ 107.39 all inclusive. See details and summaries for the models of this catalog.
