These transistors are prone to failure. One particular failure mechanism is the growth of tin whiskers from the tin-coated inside walls of the transistor case. In most cases, germanium transistors can be replaced with modern general-purpose silicon bipolar transistors with no modification to the circuit.

Alloy Germanium Power Transistors. Unlike grown junction transistors, alloy transistors could be readily scaled up for high powered audio output. Typical applications were in servo control systems and automobile radios. TI''s first power transistors were the 356 and 356A rated at 12 watts which became the 2N250 and 2N251. [Knight 2007]

 · Germanium was the first semiconducting material widely adopted for transistors, power and otherwise. One early power transistor I came across was the 2N174, shown in Figure 1. Figure 1: 2N174 Power Transistor. Following are some key maximum ratings on the 2N174 power transistor…

Now Sweetwater is excited to present guitarists with the OCD-Ge Germanium — an "old-and-improved" version that uses a pair of vintage-style germanium diodes and two hard-clipping MOSFET transistors to work its overdrive magic, just like the very earliest OCDs, before these coveted components became rare and expensive.

NKT275 transistors are among the most coveted germanium transistors and are known for their beautifully warm tones and their exceptional clean-up when rolling down the volume. Q1 hFE = 73 Leakage = 0.04mA Q2 hFE = 83 Leakage = 0.06mA Please …

 · Amplified by germanium transistors, the music died out instantly as Teal dunked one into a beaker of hot oil. But when he repeated his demonstration immersing a silicon transistor …

If Ge vice Si is an issue, and i guess non-linearities are of interest in pedals, you should search and study materials about the characteristic curves of transistors; also consider obtaining a semiconductor curve tracer so you can get a real feel...

 · 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 ...

The early IBM germanium transistors frequency applications, but the ever increasing demand for faster computers required higher switching speed transistors. IBM began development work on the high speed drift transistor technology in the mid-1950s, with its first patent filed in 1955 (see composite

 · The germanium transistor was the first to be mass-produced and made commercially available to the public. This transistor was used extensively in radio technology, helping to create the first portable AM radios, as well as the first car radios. It was even used in a few of the first guitar effect pedals in the 1960s.

One of the secrets of the tone here are the coveted Newmarket NKT germanium transistors. These medium / high gain (Q1: 91 hfe / Q2: 168 hfe) transistors are at their best pushing a slightly overdriven amp (or running into an overdrive pedal), but still clean up slightly when rolling back on the guitar volume.

The germanium alloy-junction transistor, or alloy transistor, was an early type of bipolar junction transistor, developed at General Electric and RCA in 1951 as an improvement over the earlier grown-junction transistor.. The usual construction of an alloy-junction transistor is a germanium crystal forming the base, with emitter and collector alloy beads fused on opposite sides.

Three of the most coveted legendary Germanium sounds in the same pedal. A planned Limited Run of 100 units made with hand selected NOS transistors. The transistors used in this pedal are not made anymore for decades. Specially blended together to cover the sounds of the three Germanium legends.

 · 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 ...

You can have Russian germanium transistors fitted too, if that''s your bag. I''ve also made a pedal called the Tube Overdrive Distortion Plus or TODP. It''s essentially a gain stage, into a clipping selector, into a valve, into a recovery stage – any or all of which can be overdriven - and then into a filter.

The first few years of the Fuzz Face* were manufactured using germanium transistors but by 1969, germanium fully gave way to silicon devices and Arbiter never looked back. Hendrix himself preferred the silicon versions over germanium because of their sound, aggressive bite, and their stability in environments where germanium proved inconsistent.

 · In a very close future, all stocks, including mine, of original germanium AC128 or any usable germanium transistor will dry. Forever. After this extinction, that only a few aficionados will notice, there will be no other possiblities to obtain THE original fuzz tone than a used Germanium fuzz box or a digital model.

 · Germanium Returns: Germanium was an early transistor material. Now its charge-carrying abilities and advanced fabrication technology make it an attractive material for future chips.

A transistor is a semiconductor device with at least three terminals for connection to an electric circuit the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits.The transistor replaced the vacuum-tube triode, also ...
