However, far too few people realize that to obtain good treble from a solid state power amp, one either starts or finishes with the power supply, just the same as for the bass. This work needs to be ...

The efficiency of linear RF power amplifiers in which transistors are operated as dependent current sources such as Class A power amplifier is low at low levels of the output voltage as compared to ...

Good. It follows that with 8/4/2 Ohms loads, our required currents will be (20:8/4/2) 3.54/7.07/14.14 A. Small wonder, since we want our amp to provide 50/100/200W into 8/4/2 Ohms. Remember, this is ...

so [ElectroBoy]’s dual voltage PSU board for audio amplifiers is worth a second look. This type of linear power supply has an extremely simple circuit consisting of a transformer, bridge ...

After the huge success of the acclaimed and multi-awarded Nu-Vista 800.2, Musical Fidelity is proud to announce the new ...

There are three types of amplifier – masthead, set-back and distribution. All these need a power supply to work. Some amplifiers are a mix of the above. For example, some masthead amplifiers ...

All traveling wave tubes have small, aperiodic variations in their small‐signal gain and phase responses versus frequency. The solid‐state power amplifier (SSPA) is different from the TWTA subsystem ...

Could this be your tube amp's secret weapon? AmpRxs latest allows you to control the voltage your tube amp is getting, ...

The Cyrus 40 AMP is everything we want in a modern Cyrus integrated amplifier. It’s well-built, fully equipped, looks smart and sounds excellent Optional 40 PSU power supply is effective but pricey ...
