396 RADIO BROADCAST ADVERTISER The radio leadership of 1928 New 401 Dry Cell Type BANDBOX JUNIOR #35 A new dry cell receiver with all the features of the Band- box — selectivity, sensitivity, volume and appearance. For places where AC cur- rent or storage battery ser- vice is not available or de- sired. 180 volts on the output tube plate/ Gigantic «^»/STfl/?Z£0 volume fromtheBandbox/ Power! Power! POWER! A feature of the Crosley AC Bandbox that lifts it head and shoulders above competition! 1 70 to 185 volts on the plate of the power output tube! Comparative checkings of competitive radios show interesting figures. Under identical testing condi- tions the Bandbox shows a full 170 to 185 volts on the plate of the 171 power output tube. Other radios show from 100 to 110 and 130 to 140 volts on the plate of output tube. The 171 power tube should have around 180 volts. This better than 40% superiority in one case and 25% in the other is the difference between today's radio and yesterday's. 9)ouUe 'Unit 4?BANDBOX Single Wnit MUSICONE TypeD Crostey Musicones are famous for their value. 'This new style is no ex- ception. Its low price of $15 is in keeping with Crosley traditions. It in- stantly demonstrated its soundness by immediate and enormous sales. The Bandboxes are genuine Neutrodyne re- ceivers. Totally and completely shielded, their acute sensitivity and sharp selectivity is amazing. They have a single illuminated dial. Contributing much to the success of this 1928 wonder radio is the Mershon Con- denser in the power element of the set. Not being paper, the danger of its blowing out is entirely removed so that the desired heavy voltage can be used to produce the acoustic and volume results so greatly desired. IT IS SELF HEALING. It does not have to be replaced as is the case with paper con- densers. The capacity of smoothing condensers in Crosley power units is 30 mf. Other sets use only a frac- tion of that condenser capacity. Undersize con- densers, transformers, etc., are used in order to build down to a price. Crosley builds up to a standard. The AC Bandbox is purposely made in two models—the 602 in a double unit—the 704 self contained. This is to provide maximum adaptability in all sorts of surroundings and uses. The 602 double unit provides console cabinet installation in ALL kinds of consoles. The 704 is for those who want the entire set in one cabinet. The two sets are identical in element, design and performance. The physical difference is solely to meet the human differences of taste, necessity and price! The size of the 704 is 17| inches long by 12'| inches wide and 6| inches high. Battery Type Bandbox $55 This celebrated model needs no picture, for in appearance it is identical to the 602 receiver pictured above. Its amazing per- formance has won the radio world this season and its value is as outstanding NOW as the day it was first presented.
