Philco 1N82 Transistor  
Written by AnubisTTP on 2012-02-19  


The 1N82 is a mid-1950s era germanium diode intended as a low loss mixer for use in television receivers. The 1N82 has a classic 'cat whisker' point contact, which can be seen pressing against the diode's square germanium crystal through the glass housing. Unlike some earlier devices, no provision has been included for manual adjustment of the point contact's position after installation of the diode in it's target system.
