1958 Junk Box Special

1958ElecExpHdbkSixty years ago, the 1958 edition of the Electronic Experimenter’s Handbook, an annual put out by Popular Electronics, showed this simple circuit for a broadcast receiver from parts that were probably available in the junk box of any experimenter. Most of the set’s parts could probably be salvaged from a junked All American Five receiver, including two of the tubes. The 35W4 served as rectifier, and a 12AU7 or 12AT7 dual triode was the detector and audio amplifier.
