Made in the N.S.F. factories in Hilversum.
The design of this radio is, like that of the later
receiver 2514, by ir. Louis Kalff, who also designed the
Philips disc loudspeakers. The style is "Nieuwe
Zakelijkheid" or "New Realism", a modern design,
that was not to everybody's taste. A small cabinet was
made by the Brandsteder furniture workshop
in Amsterdam, specially for this set.
In this cabinet the 2501 (or the 2502) could be placed, as
well as the battery eliminator. It is shown
here. |
|
The wave ranges are 200-400, 300-600 and
1000-2000 meters. The built-in 2503 power supply unit works on 220
Volts in this radio. The radio also requires the Philips
battery eliminator 372. |
