Seventy-five years ago this month, the May 1951 issue of Radio Constructor showed how to build this handsome three-tube (including rectifier) broadcast receiver. It covered both mediumwave and longwave (1225-2000 meters). A 15-foot antenna would pull in the mediumwave broadcasts, as well as the BBC Light Program and Radio Luxembourg on the longwave band. The detector was regenerative, and the author had to work out some tricks to keep the regeneration (or reaction, as they called it) stable even if the line voltage varied.
