audioXpress November 2014 Is Now Available Online.

The November 2014 edition of audioXpress is dedicated to our DIY audience with the first instalment of a rewarding project on “How to Build an Audio Mixer“ by George Adamidis. We also have two great articles on audio amplifiers: one is Class-AB MOSFET-based and the other is a push-pull AB amplifier using KT 120 vacuum tubes. Of course, we continue to discuss the latest Wireless Audio technologies and Audio for Mobile Devices. In the third article in the Nordic Audio series, we explore Scan-Speak’s audio history. We also bring you an article explaining the thinking and product design considerations for the unique Genelec M Series studio monitors. That and much more is already online.

Luciano owns LPJ Audio, a small business that designs and builds pre- and power vacuum-tube amplifiers. He also teaches analog electronics and digital techniques in a federal technical school in his hometown.

MXL Microphones is marking its 20th year with special edition gold and pearl white versions of three of their most popular microphones: the Genesis SE Tube, R144 SE Ribbon, and 2001 SE Condenser. The special edition microphones retain all the characteristics of the original mics of the same names.

Wathen Speakers introduced its new Wathen CryoTone Tubes at the Summer NAMM 2014 in Nashville. According to the company, Wathen CryoTone tubes use a cryogenic treatment process that is specifically designed to maximize sonic performance in tubes, expanding its dynamic range, while also increasing its reliability.

The new Yellow Jackets NOS (New Old Stock) Tube Converter, designed with an NOS 6AQ5 seven-pin miniature beam power tube, is a limited edition converter made for use in most amplifiers under 100 watts and using 6L6, EL34, 7027 or 6V6 output tubes. The converter lowers the overall power in an amplifier and gives that amp a unique vintage tone.

Universal Audio announced the release of its new Thermionic Culture Vulture Plug-In for the UAD Powered Plug-Ins platform and Apollo audio interfaces. This is a circuit emulation of the legendary British-made Thermionic Culture“all-valve” boutique distortion hardware. Uncanny!

Linear Audio Volume 7 is the eight issue of a series of printed bookzines dedicated to technical audio and perception. Compiled and published by our technical editor, Jan Didden, this series of bookzines aims to help spread technical audio information and knowledge in printed format.

You can build a tube amplifier that's similar to the original Nardeux Stereomatic 302 S. Follow these steps to create a powerful amplifier that produces satisfying music output.

With a little know-how and some basic parts, you can design a hybrid amplifier in fairly short order. This project combines the best attributes of both tube and transistor technologies.

Which sounds better — a tube or solid-state amp? The "Great Debate" has been going on for decades. Now it's time to put the debate to rest. In audioXpress, November 2012, Richard Honeycutt's published this article exploring how to detect audio amplifiers’s differences in sound and the need for a correct subjective evaluation process of components and systems.
