There is so much to learn about the single-transistor amplifier, that this brief tutorial hardly scratches the surface. This discussion considers only the common-emitter configuration as applied to ...

Members can download the PDF ebook. One day, back about 1966, I was going up the elevator at 285 Columbus Avenue in Boston to look at some production problems on Philbrick’s fifth floor. And who was ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

Q: What is the difference between a hybrid amplifier and a tube amplifier? I have seen both advertised, and both seem to use tubes. Is there any difference? — B.P., Youngstown, Ohio A: Tube amplifiers ...

I have recently discovered that finding the perfect loudspeaker is an amazingly daunting task. I’ve explained in the first part of this saga what it was like finding a near-perfect pair of Quad ESL-57 ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...

Kevin Aylesworth is a Senior Program Officer at the National Research Council. Although his job these days revolves around science policy rather than building things in the lab, Aylesworth—an ...

On November 17, 1947, Walter Brattain dumped his whole experiment into a thermos of water. The silicon contraption he'd built was supposed to help him study how electrons acted on the surface of a ...
