1N34A Germanium Diodes & The Diode Detector Report

Here are the classic 1N34A GERMANIUM DIODES which have been specified in countless crystal radio plans and projects for decades.  These high sensitivity point contact diodes make excellent detectors for all your AM crystal radio projects.  Also included is our 11 page DIODE DETECTOR REPORT, with performance comparisons on 33 different types of diodes from around the world, as collected and tested by MTM Scientific, Inc. Of all the diodes we tested, we found one vintage German diode (no longer in production) had the best low-voltage-drop performance. We will include a sample of that diode with the packet of 10 pieces 1N34A Diodes and the Diode Detector Report... All sent by First Class Mail, for only $12.50

Specifications: 1N34A, Germanium, Point Contact, Vf = .35 Volts @ 1 mA  (Click here for I-V curve)

Please note: The 1N34A diodes can be used in almost any crystal radio project calling for a diode as the detector, such as 1N60, 1N34, etc.  Some common older terms for detectors are: rectifier, coherer, cat's whisker, galena and crystal.

Diode Mix Pack

In the course of collecting diodes for testing from around the world we have accumulated a huge assortment of different types.  Therefore we are offering a DIODE MIX PACK for experimenters interested in exploring diode performance. You will receive 10 different diodes, mostly point contact germanium types. No two packs will be the same, and each diode will be individually identified and labeled.  This assortment is a great way to try different diodes in your crystal radio projects.
