Screen-Grid Tube 245 Power Tube THE RADIO WORLD'S FAIR An Analysis of the New Receivers Dis- played at the Radio Show at the New Madison Square Garden, New York City. SUMMARY of the exhibits of receiving sets at the New York Radio World's Fair has been made by RADIO BROADCAST. The results are presented here in the hope that they will be useful to the entire trade. A similar survey was made of the exhibits at the Chi- cago Radio Trade Show last June and was published in RADIO BROADCAST for July, 1929. Comparisons between the two exhibits are somewhat difficult, due to the fact that exhibitors at the two shows were not exactly alike either in number or in name. The purpose of this survey, however, is to summarize the salient facts and to give a general picture of the industry's present offerings of radio sets. Our summary shows—in figures—what the trade in a gen- eral way knows: the console model still rules supreme, the dynamic loud speaker is on top of the heap, there is a wide range of offerings in the medium-price field, the phono- radio combination is returning to favor, screen-grid models predominate, and prices are, on the average, only a little higher. Two tables show in compact form what the offerings to the trade and public are and how they compare with the first-season offerings at the Radio Trade Show in June. 1. How about screen-grid models? Somewhat more than half of the models at the show used the screen-grid tube.

The trend toward the more general use of the tube is shown by the fact that our survey at the Chi- cago show indicated the use of this tube in only 45 per cent, of the models. 2. How about prices? At the show 141 models were classified. Sixteen were priced at less than $100, 27 at from $100 to $150, 42 at $150 to $200, 34 at $200 to $300, and 22 at more than $300. Sixty per cent, of all the models listed at $200 or less. At the Chicago show 65 per cent, listed at $200 or less so, in general, there hasn't been any definite change in price trends since June when the Chicago show was held. Table model prices do, however, average somewhat NOVEMBER 1929 11
