Germanium Transistors Logic Circuits In The Ibm 1401

The wafer-based mesa transistor was invented in 1958, followed by the modern planar transistor in 1959. Thus, transistors were undergoing radical changes in the 1950s and IBM introduced new logic families to take advantage of these new transistor types. Conclusion. Diode-transistor logic was a key part of IBMs early computers such as the IBM 1401.

Germanium Vs Silicon Transistors Robert Keeley

Sep 11, 2013 Germanium is a chemical element with symbol Ge and atomic number 32, thats 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 ...

Replacing Germanium Transistors Antique Radio Forums

Apr 03, 2018 Additionally, Germanium transistors usually didnt have as much gain as was neededwanted, leading to circuit design decisions that would be considered really bad today. Germanium circuits are often overly sensitive to Hfebeta by modern standards. If you are going to mess around with Germanium, build a test fixture like this one.

Identification Germanium Transistor Electrical

Apr 17, 2020 The one with the higher voltage drop will correspond with the emitter of the transistor. figuring out collector from emitter is a bit harder. You can do it with two 9-volt batteries and a 3.3K resistor if you hook them all in series with a transistor, in one of the configurations the transistors EB junction will zener at around 6 to 15 volts.

Germanium Transistors Electronics Forum Circuits

Mar 16, 2021 Mar 15, 2021. 8. Compared to silicon devices, germanium ones have a lower forward voltage and a softer knee, the roundness of the onset of forward conduction. Both of these are desirable characteristics for a guitar effects pedal. The lower forward voltage and saturation voltage in a power transistor means less power dissipation.

Nov 07, 2007 Its so cool - you dont even have to know the pinout of the device your testing, just hook it up and it tells you the pinout as well as all the other necessary info. Good transistors for Fuzz and Booster are Russian MP20 and MP21 Germanium PNP the GT311 is Germanium NPN. I use these transistors for Booster Clones.

Replace Germanium Transistors With Silicon Pnp Ones

Mar 31, 2021 Silicon transistors started replacing germanium but I guess not quick enough for that article. As mentioned, you want to use the PNP version like a 2n3907. And keep in mind that while they work in similar manners, germanium diodes have a forward voltage of 0.20.4 volts on average, while silicon will have 0.6 to 0.8 volts.
