AC/DC TRF Superferodyne receiver

With black bakelite cabinet and white knobs. Three valves (+ rectifier), French scale. In green: medium wave stations, in red: long wave stations. In Great Britain this radio was released in March 1936; the radio pictured above was made in Belgium. The radio operates on 110 and 250 volts AC or DC.

To overcome import restrictions on the continent, Ekco set up a small-scale manufacturing and distribution site in Belgium: S.A. Ekco Radio, Avenue de Schaerbeek, Haren (near Brussels), as import duty was levied by weight. The company initially used components shipped over from Southend but gradually began to use locally sourced components.
This manufacturing unit, however, was short lived due to an economic downturn in Belgium. In 1937 it was shut down with the exception of a sales and service department in Brussels, which continued up to the start of WW2.
Continental tubes EF5, EF6, CL4 and CY1, heater circuit ballast and capacitors were used in this set. In the English version the tubes VP13C, SP13C, Pen36C and UR1C were used. The dial lamp was also changed in the Belgian model. The English model has a large 200V lamp; in the continental version a much smaller lamp in series with the filament circuit of the EF5 detector tube was used.
