Superheterodyne receiver
In Bakelite cabinet with reddish brown lacquered wooden panel behind the knobs. The knobs form left to right: tone control, on/off/volume, wave range switch, tuning.
With medium wave (160-585 meters) and two short wave ranges (13,7-45 meters and 45-160 meters). The intermediate frequency is 452 kHz.
The scale is illuminated form the back. The scale lamp is a heavy duty one (Philips 8091D: 6,3 volts at 0,64 A). The indicator is made of rod-shaped glass lens, the tuned station is shown by a stripe of light.
A connection for antenna and earth are situated at the back, as well as a connection for a gramophone and an extra loudspeaker. A switch makes it possible to choose between radio and gramophone.
A date stamp on the loudspeaker indicates that the radio was made in September 1940. The radio was used in the former Dutch East Indies and returned to the Netherlands after WWII. With many thanks to Daan Alers, who gave me this radio.
The original price was f 187,50. There was also a radio for AC/DC: the 494U. The price of that receiver was f 205,-.
