Seventy years ago, the January 1956 issue of the British magazine Radio Constructor had the plans for this handsome “transportable” six-tube (including rectifier) receiver for the medium and long waves. The set was a superheterodyne, and was said to perform well even in weak signal areas. It earned status as transportable and not portable due to the fact that it ran on AC power.

The main innovation was the use of a ferrite antenna coil, which outperformed earlier built-in antennas.
