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. The receiver has grid-leak detection. 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.

Both tuned coils have an iron core; this may explain the name "Superferodyne", used for the radio made in Haren.
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.
The factory only had a short existence. Due to the deteriorating Belgian economy, Ekco Service was dissolved on December 30, 1937. Ekco Radio also fell in 1938.
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 200V/12W lamp; in the continental version a much smaller lamp in series with the filament circuit was used.

In 1942 Ekco still advertised for the radio. Radios for the consumer market were virtually no longer produced, but they continued to advertise to hold the brand's reputation.
