Germanium - Wikipedia
Germanium is een scheikundig element met als symbool Ge en atoomnummer 32. Het is een vrij hard grijswit metalloïde, dat behoort tot de koolstofgroep.Zuiver germanium is een halfgeleider.. Net zoals het vergelijkbare element silicium komt het in de natuur niet in zuivere vorm voor, maar gebonden aan andere elementen, zoals zuurstof.Het komt voor in verschillende mineralen, zoals argyrodiet ...

Germanium Transistor Linear. 2013-7-13if you were to substitute that germanium pnp transistor with a modern pnp silicon transistor, what transistor would you select if you bias it into its linear region it would work as an amplifier and boost the rf level.
Substitution of old germanium transistors in radio ...
13-7-2013 · If the transistor had no bias at all, it would not conduct until the received signal reached about 0.5V which is far more than you would pick up from anything but a radio station right next door. If you bias it into its linear region it would work as an amplifier and boost the RF level athough C4 might make the gain useless.

How to test germanium transistors? - Antique …
Transistors are tested the same way whether they are silicon or germanium. However, the expected results differ somewhat depending on what type of transistor you have. Assuming you have identified the leads of the transistor, what you are basically looking for is two diode junctions, one between the base and collector and the other between the base and emitter.
Germanium vs. Silicon Transistors - Robert Keeley
Germanium is a stone element with symbol Ge and atomic number 32, that’s used as a semiconductor in transistors and diodes, popping up in a few classic effects like the early period Arbiter Fuzz Face, the storied Dallas Rangemaster and the Maestro Fuzz-Tone. “Subjectively the sound of Germanium offers a smoother, more-ear pleasing distortion.

Hoe werkt een transistor? - IDEM DITO
Transistoren bestaan uit halfgeleidermateriaal zoals germanium of silicium. De atomen vormen een kristalstruktuur en zuivere germanium of silicium zijn een redelijk goede isolator, maar door onzuiverheden in het kristal kunnen electronen loskomen van hun atoom en zo wordt germanium en silicium gezien als een halfgeleider.
