These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically range of wavelengths depending on ...

These home made transistors sacrifice a point contact diode to get the small chip of germanium, and form the other two electrodes with metal foil glued to paper. Given that germanium point contact ...

and GE/ASYM which uses a vintage germanium diode to create asymmetrical, even-order harmonic distortion. Tested with single-coil– and humbucker-equipped electric guitars, and run through a ...

From its germanium clipping diodes, which allow for dynamic playing, to its vintage-style all-metal housing (a rarity for Behringer) and gold finish, the pedal is uncannily Klon-like, albeit in ...

One of the graduate students, Seymour Benzer, accidentally discovered that a crystal of germanium -- a semiconductor which was not well understood at the time -- could withstand higher voltage ...

Voila: two gold contacts just a hair-width apart. The whole triangle was then held over a crystal of germanium on a spring, so that the contacts lightly touched the surface. The germanium itself ...
