1971 Six Tube British Superhet

1971JanRadioConstructor1This utilitarian-looking receiver appeared fifty years ago this month in the January 1971 issue of the British Radio Constructor magazine. Complete with its own coat of arms, the set was dubbed the Crusader, and tuned longwave (150-375 kHz), mediumwave (545-1546 kHz), and shortwave (1.85-18.75 MHz). Even though it was billed as being for the near beginner, the 6-tube set was a superheterodyne, and probably did an admirable job of pulling in the weak stations. Construction was simplified by the pre-assembled coil pack, which is undoubtedly unobtainium today. It featured a transformer power supply, making it a safe set to operate from the AC mains.
