1962 One Tube Radio

1962SpringRadioTVExp3Some of our readers are beginners, but we have no doubt that they are serious beginners. Therefore, we are sure that this one-tube broadcast receiver from 1962 will be of interest. The chassis is made of plywood, and empploys a singe 6SN7 tube. Half of the tube serves as a regenerative detector, with the other half amplifying the audio. A “dry” rectifier is used in the power supply, although a semiconductor diode could just as easily be substituted. The chassis was made of plywood, handsomely stained, and the result was an effective personal or bedside receiver, sure to provide the maker with many pleasant experiences. The project appeared in the Spring 1962 issue of Radio-TV Experimenter.
