The General Electric model P1740 is the first IC radio ever. According to the "Electronics World", November 1966, page 44 fhrough 46 there is an article by Cacciola, J.A. / Carr, E.Q with title "World's first Single-Chip Integrated-Circuit-Radio". With the model comes a battery charger for the internal accumulator (storage battery). There are two versions (see pictures): one without the other with a clock radio, both having a bigger loud speaker which is automatically switched on when playing on the connected docking station type charger (model C-2450). The set has no transistors and we don't know the number of transistors in the ICs.
By the way: in Spring 1967 Heathkit sold the AR-15 AM-FM radio with two ICs CA3012 from RCA. Philips was the follower in Europe for an IC radio - with the model IC2000 - introduction "Funkausstellung" 1967. At roughly the same time Sony Japan was marketing their first IC radio as IC100.See also model C-2450A.
