Historical Background

The transistor was invented at Bell Labs in December 1947, with the first public announcement in June 1948. The first transistor type was known as point contact, which consisted of a small piece of germanium in contact with two sharp metal points. Rapid improvements were made to this technology and by the late 1950s the germanium alloy junction transistor type was the most common, manufactured by such companies as Raytheon, GE, RCA, Sylvania. Silicon technology largely replaced germanium in the 1960s. Your Experimenter’s Pack #1 includes four vintage 1950s/60s germanium alloy junction transistors, each tested and matched to the specifications included and required to build the classic circuits also included. This TransistorMuseum™ Experimenters Pack provides an educational and entertaining way to learn about the history of the transistor. In addition, we hope you’ll also experience some of the same excitement and pleasure that transistor technology kits provided to young electronics hobbyists and experimenters in the early days of transistor technology.

Shown above is one of the pages of the six page color insert supplied with your kit. This is a schematic and project description of a three transistor AM radio tuner, based on a classic 1950s GE transistor manual project. You can build this project with three of the four transistors you’ll receive in your order - these are shown above as well and are the GXP- 1, GXP- 2, and GXP- 3.

**********

Shown above are examples of the types of transistors that will be supplied with your Experimenter’s Pack #1. All the transistors are vintage 1950s/60s, each has been individually tested (or is still in the original manufacturer’s packaging) and is guaranteed to work in circuits using the supplied specifications.

This is a photo of a section of the transistor specification and historical transistor type equivalence table supplied in the color insert. Shown are the specs for the GXP– 4 transistor and list of possible types that could be included in your order for the PNP Low Noise Audio Preamp.

Here are some photos of what you’ll receive as part of your Germanium Transistor Experimenter’s Pack #1. Shown above are the four individually labeled and packaged vintage transistors. On the right is a photo of one of pages from the six-page color insert. This page has a chart of the various types of vintage transistors that meet the specifications for each of the GXP types in your kit, and could be supplied in your order.
