Notes

This CN-113 Crystal Receiver covered a frequency range of about 33 kHz to 1 mHz, and it included a built-in crystal detector.  Binding post connections were provided to allow it to be used with an external vacuum tube detector in a regenerative circuit or an alternate crystal detector.  The switch in the center determined whether the crystal detector (the "DET" position) or the vacuum tube ("AUD" position) would be used.  At the time, tubes were still generally called "Audions", the name given them by Lee DeForest, who invented the triode.
