We know way too little about this subject but hopefully [Bob4analog] helped us learn a little bit more this time around. He’s building his own linear amplifiers on what looks like sheets of MDF. This ...

Even with the rise of cellular communications, radio networks remain an important part of business communications, especially for small businesses such as trucking and security companies. Proper ...

The tube audio amplififer was designed using SRPP 12SL7 tubes as the driver stage and SIPP KT88 tubes as the output stage to produce a Class A Ultra Linear Amplifier. This amplifier can be regarded as ...

There was this fellow, Rudy Severns, who many years ago went on a speaking tour for International Rectifier to discuss “Hexfets,” their power MOSFETs, when that product line was still new. If memory ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

The TGA2535-SM linear power amplifier operates from 10 GHz to 12 GHz providing an output of 43 dBm OIP3. The TGA2535-SM linear power amplifier operates from 10 GHz to 12 GHz providing an output of 43 ...

A few years back, [Gio] decided to try his hand at building a couple of tube amplifiers. The first amp was more of an experiment to see how well a DIY single-ended tube amp would sound. The amp is ...

Can a stripped down Linear Tube Audio MZ3 deliver the same experience for only $2,100? The LTA Velo makes it debut this weekend at CAF 2023. One of my favorite pieces of hi-fi gear in the entire world ...

Understanding the capabilities and differences of linear and pulse-width modulated (PWM) AC power sources is especially helpful when determining which models meet your requirements. And, the selection ...
