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 ...

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.

This application note presents the ISL73096RH/ISL73127RH/ISL73128RH transistor arrays and focuses on designing RF amplifiers employing these featured transistor ...

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 ...

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 ...

Someone brought a dead Marantz amplifier to [Lansing]’s attention, a rather nice model from the 1980s with one channel entirely dead and the other very quiet. His account of its repair is ...

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 ...

Research that capitalizes on the wide-ranging capabilities of graphene could lead to circuit applications that are far more compact and versatile than what is now feasible with silicon-based ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...

There appears to be 16 large transisitors which were mounted to the heatsink of this amplifier. It is a Planet Audio 4 channel car audio amp. From some quick Google searching, it looks like I should ...
