The Marconi T25DA is a compact British valve radio from the early 1950s. It was designed as a relatively small domestic wireless set that could be moved conveniently between rooms, although it had to be plugged in to a mains wall socket.
It’s an interesting example of post-war British radio engineering, combining a five-valve superheterodyne circuit with an attractive cream-coloured cabinet and an internal aerial.
