Four valve homodyne (direct-conversion) receiver.
In oak cabinet with doors. The doors are decorated with coromandel wood. The top has a hinged lid with snap closure.
The knobs from left to right: rheostat for the mixer valve with the text "zwak/sterk" ("strong/weak"), antenna tuning, wave length switch with two push/pull switches, the upper one for the scale lights (remarkable for a battery set) and the lower one switching off the filament circuit of the valves, followed by oscillator tuning and reaction control (phase control for the oscillator). This remarkable circuit has not been frequently used in commercially manufactured receivers.
