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 ...

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

The goal of this series is to maximize the voltage gain of the single transistor amplifier. I had always thought that hFE had a profound effect upon voltage gain, so I set out to determine how ...

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.

Now, a team from MIT and elsewhere has broken through this bottleneck by embedding GaN transistors into an ultrathin layer of diamond. The diamond acts as a heat spreader that normalises the ...

The silicon that forms the foundation of most computer chips has fundamental limits to how much power it can manage, which ...

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 ...

San Francisco, CA. Qorvo at IMS 2016 highlighted several new products and features. The company debuted six new 50-V GaN transistors and said that its QPD1000 15-W GaN on SiC wideband input-matched ...

By using a thin layer of diamond to manage excessive heat, researchers can boost the speed and energy-efficiency of ...

The new 200W McIntosh MA352 Integrated Amplifier brings vacuum-tube technology and solid state components together in a unique hybrid design. Classic American audio brand McIntosh Labs – the brand ...
