A Sensitive Crystal Reciever

The following circuit was published in January 1958 in Radio Constructor Magazine.
One unique feature is the biasing used to make the set more selective. It uses GEX 34 diodes and a Teletron HAX coil
I do have the coil so I intend building this set so watch this page for more information.
