In this early type of radio receivers, the electrical components
were assembled in beaufiful handicrafted wooden base. Soon there
was a strong demand for an enclosed or cabinets following classical
furniture styles. The radio boom forced the manufactures to developed
mass production, launching in the market more economical one-dial
radio sets. In the early thirties the home radio receiver had acquired
its own shape through the industrial desing hence arising a cluster
of cute aesthetical concepts.
The new stylized cabinets had sophisticated wood finishing by using
lacquers and varnishes. Therefore, in spite of the industry’s
continuous effort to improve even more production processes, the wooden
cabinet was still an expensive manufacturing item. Fig. 310
