Germanium and Silicon in Fuzz What’s the Difference

Jul 27, 2018 Transistors play a vital part in the design of this effect and their germanium and silicon diodes can sound quite different in the final result. The transistor is considered to be one of the most important inventions of the 20th century, perhaps even, of all time.

What is a Germanium Transistor? (with picture)

May 16, 2020 A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a silicon-silicon-germanium alloy is commonly used to increase transmission speed of electrical signals. Individual electrical component speed adds up as an aggregate, and, therefore, a germanium transistor array can significantly increase the processing speed of a circuit.

May 10, 2013 And during much of the 1960s, even then commonly available germanium output power transistors like the now extremely rare AD 149 PNP germanium output transistor which can produced 10 watts in a single-ended configuration if properly heat sinked remains under utilized by electronic enthusiasts of the day because back then heat sinking

Germanium vs. Silicon Transistors Robert Keeley

Sep 11, 2013 Germanium is a chemical 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

Germanium Transistor cross reference Music Electronics Forum

Sep 03, 2012 The forward voltage of a germanium diode and a silicon diode differs so much that if you use clipping diodes, you have to pre- and post-amplify by different amounts to get even notionally equal drives on the diodes and output signal levels. The same thing applies to use of silicon versus germanium transistors.

Silicon vs Germanium Vacuum tube audio amplifier [H]ard

Feb 26, 2019 During Christmas I was visiting my parents and had interesting talk with my dad. He claimed germanium transistors do have "transistor sound" it is different and overall sound somewhat closer to vacuum tubes in that they sound softer and more natural because of different voltages they start to work at and other electrical characteristics and effects.

How to Test a Transistor & Diode » Electronics Notes

As with the germanium diode, the reverse readings for germanium transistors will not be as good as for silicon transistors. A small level of current is allowable as this results from the presence of minority carriers in the germanium. Analogue multimeter overview.

Articles › Transistors in Vintage Radios

It's true that silicon transistors are better in most regards, but used appropriately, germanium transistors can give excellent results, and generally, they are remarkably reliable especially when you consider how young the semiconductor industry was but

Testing Germanium transistors Details Hackaday.io

So I had 3 transistors in my archives, one 2N1926 and two 2N396. My first test with the attempted Xtal oscillator failed. I had tested the 3 with my DMM and found inconsistent results.

Testing Germanium Transistors For Leakage and Gain Crawls

Sep 09, 2011 Now that I have become Transistor Boy, I am learning all about them. Well, let me restate that. I am learning some basics about them, and what I am learning is pretty much 30-40 year old technology. Anyway, what I do know is that germanium transistors have a reputation for good tone in fuzz/distortion devices.

How to test germanium transistors? Antique Radio Forums

Gentlemen, I am new to the transistor world so I have a lot to learn about testing transistors. The radio I am working on is equipped with germanium transistors and from what I have gathered from watching U tube videos and other sources that germanium transistors are tested differently from other types .

Characterizing Germanium Junction Transistors

the results obtained with respect to three types of germanium junction transistors as well as a comparison with results previously [1] obtained for 7 complementary types of silicon transistors. II. EARLY MODELING AND CHARACTERIZATION In 1952, an interesting electronic e ect taking place in junction semiconductors was reported by J. M. Early, in

Germanium Can Take Transistors Where Silicon Can’t

Nearly 70 years ago, two physicists at Bell Telephone Laboratories—John Bardeen and Walter Brattain—pressed two thin gold contacts into a slab of germanium and made a third contact on the bottom of the slab. The flow of current through this configuration

Germanium Wikipedia

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

Jul 19, 2009 How does the leakage affect the tone in the long run and how long is the long run? I mean, how long can a germanium transistor be used? J. JLee. Supporting Member. Messages 2,637. Jul 18, 2009 #2 Excessive leakage can result in excess noise at idle and have an effect on the performance related to temperature. Meaning it would be more prone to

Face the Fuzz: A Beginner’s and Skeptic’s Guide to Fuzz

Oct 10, 2017 Along with their appealingly organic sound, germanium transistors can exhibit wide swings in tolerances, meaning any two—or 10—coming off the assembly line side by side rarely sound exactly the same. Aware of this phenomenon, good latter-day makers test and sort germanium transistors to find those that perform as desired.
