with two gold coloured metal ornaments and a glass
station scale. On the left tone control (also serves as
on/off switch) and volume control; on the right the
wavelength switch. The radio has medium
wave, long wave and 2 short wave bands. The receiver
uses two batteries: 1.5 volts and 90 volts. The
batteries can be placed inside a battery compartment (see
picture below). An economy switch on the back of the
radio makes it possible to prolong battery life. The
radio then uses 11 mA instead of 19 mA by interrupting
the filament circuit of one DAF91 and one DL94 tube.
When the radio is used as gramophone amplifier, the
filament circuits of DK92 and DF91 are interrupted to
save the batteries.
