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.

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

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 ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

This monograph is concerned with the application of transistors to the audio-frequency amplifiers employed in sound broadcasting for which a high standard of performance is required. The prinicples ...

Millions of guitar player can’t be wrong. Well over 80% of guitar amplifiers new and existing still use vacuum tubes. Based on my experience, that could really be over 90%. Nevertheless, most guitar ...
