Key takeaways

  • Western Electric (tube manufacturer) belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Western Electric (tube manufacturer) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Western Electric (tube manufacturer) from memory before moving on to harder problems.

Reference excerpt

Western Electric Export Corporation (or simply Western Electric) is a manufacturer of vacuum tubes and high end audio gear. Based in Rossville, Georgia, the company builds an ultra-premium version of the 300B electron tube. It traces its roots to 1872 with the Bell Telephone Company and the original Western Electric. The original AT&T-based company was shut down in 1984. The successor was started in 1995, when AT&T granted Charles G. Whitener (Westrex Corporation) a license to the trademark and intellectual property of the original Western Electric company. In January 2007, Western Electric announced the acquisition of the assets of former vacuum tube factory Ei Niš from Serbia. The company has announced it will manufacture vacuum tubes for musical instruments, such as electric guitars.

300B Few factories make tubes of any kind as the market for these devices is small. Tubes have generally been replaced by transistors, which are smaller, much more efficient, produce less heat and are less expensive. However, there still exists a few markets for tubes, such as high end audio reproduction and many electric guitar amplifiers. The product line consists of solely the 300B, which was designed for use in telephone amplification in the 1930s. By the 1980s, they found use by audiophiles. Western Electric's tubes are considered "ultra-premium", designed for audiophiles who want the best and are willing to pay for it. In 2020, the price for a matched pair of these single-ended tubes was $1499, while a matched quad cost over twice as much.

Guitar amplifier tubes In March of 2022, Western Electric announced it would soon be producing tubes for the guitar tube amplifier market including the 6L6, EL34, 6V6, EL84, 12AX7 and others. This comes as most nations have banned imports from Russia because of the 2022 Russian invasion of Ukraine. At the same time, Chinese manufacturing is being phased out, leaving only a single factory in Slovakia (JJ Electronic) as a ready source for these vacuum tubes. The existing 300B tubes are quite different from tubes used in guitar amps, however many parts like the base mounts are identical, as well as the glass being made from the same material. Western Electric also completed a major expansion of their Georgia facility, a two-year undertaking that moved production to the Rossville location and expanded room for production. According to company sources, the jump from making 300B to these other models is not that big a step because of the use of similar materials. The company expects the American-made tubes to be more expensive than compatible tubes from Russia or China. It confirmed that it has no intention of expanding manufacture outside of the United States. According to a Wired article from March, 2023 the first new U.S. made small signal tubes manufactured will be the type 12AX7.

Other products In 2022, Western Electric began production of the 91E amplifier system, employing the 300B tube in a single ended configuration. The amplifier is a high-end model designed for audiophiles, costing $15,000 or more. It can produce from 14 to 20 watts (at 8 ohms) per channel. This is considerably more than the standard 10w per channel from a typical 300B amplifier. Like all their products, the amplifier is built in America.

Worked examples

Example 1 — a first encounter with Western Electric (tube manufacturer)

Start with the simplest possible case. Write down what Western Electric (tube manufacturer) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Western Electric (tube manufacturer) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Western Electric (tube manufacturer) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Western Electric (tube manufacturer)

In research
Western Electric (tube manufacturer) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Western Electric (tube manufacturer) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Western Electric (tube manufacturer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio equipment manufacturers, Former Bell Media networks, Guitar amplification tubes, so understanding it makes those chapters shorter.
In everyday life
Look for Western Electric (tube manufacturer) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
