TRF receiver

Walnut veneered front, black Bakelite feet, knobs and illuminated dial surround with the text "Erres Radio". The receiver has two wave bands: medium wave and long wave. The radio has a 6 watt power tube and a dynamic loudspeaker.

Because of the rather simple design and the low price, the radio was described in the
press as a "people's receiver" when it was introduced at the 31st Autumn Trade Faire in Utrecht. (Source: Limburgsch Dagblad of Thursday, September 13, 1934).
The knobs from left to right: on/off/volume control, tuning, wave length switch, reaction control. At the rear are connections for an additional loudspeaker, a gramophone and aerial and ground buses.
A "Selectivator" (separating filter) is built-in in the back panel.
The original circuit mentions a AF1 as detector valve. This valve was never made, but is identical to the E446.
The original price was f 98,-.
