Two circuit a.c. receiver
Made in the N.S.F. factories in Hilversum. The design of this radio is, like that of the earlier battery receivers 2501 and 2502, by ir. Louis Kalff, who also designed the disc loudspeakers. The style is "Nieuwe Zakelijkheid", or "New Realism". Not every customer liked this modernism, and radio cabinets were designed to hide the radio from view. An example of a radio cabinet, made by the workshop of A. Brandsteder in Amsterdam, can be seen here
The wave ranges are 200-400, 300-600 and 1000-2000 meters. The weight of this small but very compact radio is remarkably high: a little over 8 kg!
