OJAS is the creative pen name of Devon Turnbull. As a university student studying Audio Engineering he started using the name across a variety of disciplines including graffiti, music, graphic design and clothing design. In 2003 Turnbull co-founded the clothing brand Nom de Guerre with Isa Saalabi, Wil Whitney and Holly Harnsongkram. For the next decade, while primarily working in fashion, the name OJAS was kept alive on sound sculptures Turnbull was crafting for himself and a growing number of audio enthusiasts around the world. With a particular interest in high efficiency speakers and low powered tube amplifiers, Ojas audio equipment aims to bring realistic, natural sound to the listener. These products are the result of two decades of experimentation, engineering and explorations in the audio underground.

The Nature of Sound


Sound is considered to be of two kinds, one a vibration of ether the other a vibration of air.
The vibration of ether which cannot be perceived in the physical sense, is considered the principle of all manifestation the basis of all substance the “music of the spheres” it forms permanent numerical patterns which are the basis of the worlds existence, this kind of vibration is not caused by physical shock as are audible sounds. It is therefore called anahata “unstruck”, the other kind of sound is an impermanent vibration of air, an image of the ether vibration. It is audible and always produced by a shock. It is therefore called ahata or “struck”.
Struck sound is said to give pleasure. Unstruck sound leads to liberation (Narada Purana).

This magazine is a reprint of "A Study of Vacuum Tube Amplifiers of the Past," which was published in 2008.

The vacuum tube amplifiers featured in this magazine are those that appeared from the time before the appearance of LP records to the heyday of vacuum tube amplifiers, that is, from the 1930s to the 1960s, which excited the hearts of audiophiles at the time and have always been admired (and of course, they are still popular today, and can be called "world heritage in the audio world") - for example, Marantz Model 7+Model 9, McIntosh C22+MC275, QUAD 22+QUAD II, etc. We wanted to introduce these in as much detail and as attractively as possible.

In other words, we will not only introduce the products, but will also explain in detail the background and history of the development of each model, as well as the technical and functional features of each model, using circuit diagrams and a wealth of photographs and explanatory diagrams. Of course, we will also feature an abundance of attractive photographs unique to stereo sound, visually appealing the charm and greatness of the amplifiers of the past.

Therefore, this magazine will be an indispensable "book to keep by your side" for veteran audiophiles and vintage audio shops alike, as a bible of the vacuum tube amplifiers of yesteryear that left a glorious mark on the history of audio.
