[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers ...

Enter an old Radio Shack P-Box stereo amplifier kit. After a few modernizations and tweaks, the result is an 8-transistor stereo amplifier that’s aesthetically pleasing, sounds great ...

Single transistor holds the potential to power a high-performance amplifier with the right components and setup. By following precise techniques, this transformation enhances audio output ...

If the base current varies, so does the output current, which is how a transistor functions as an amplifier. It’s similar to the way you control the flow of water with a faucet. With a small ...

Audio Research's 'finest-ever power amplifier' is the culmination of 55 years at the apex of valve amp design and boasts a huge 330W of power.

The first transistor was about half an inch high ... This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold contacts, another ...

"We are excited to enhance the performance of our audio amplifiers using Infineon's GaN power semiconductors, enabling us to inspire people and provide entertainment by amplifying music around the ...

Furthermore, a transistor can also be partially turned on, a feature crucial to building amplifiers. Semiconductors play a pivotal role in this context. Contrary to conductors like metals, which have ...
