Superheterodyne receiver

Black Bakelite cabinet with chromium knobs and chromium ornaments in front of the loudspeaker and station dial. The receiver has a backlit tuning scale pointer. The design is probably by Wells Coates. He also designed a matching black wooden table for this radio. A redesign by Serge Chermayeff was released in 1935 as AC86. The radio has six valves, automatic volume control, noise and image suppression. Provision is made for the connection of a gramophone and a high impedance external loudspeaker.

The intermediate frequency is 110 Kc/s.
The walnut models blended in well with the more traditional interiors of that time. The black and chromium models were favoured by people who liked the modern architecture of that period. A good example of this style is the former Daily Express building on 120, Fleet Street, London (picture below). It was constructed in 1930-1932.
The façade has large windows and black Vitrolite panels with chromium strips. This architecture is characterised by clear, bright spaces with white walls and austere furniture.
The original price was £13 12s. 6d. for the walnut model, £13 13s. for the black and chromium model and an additional 10s. 6d. for a 25 c/s mains model. A rare white model was also reported. The battery version is the B85.
