High Frequency Apparatus - Its Construction and Practical Application #226628

In this work, I have spared no effort to produce a treatise. Of practical value. Theory has been ignored chiefly because it would serve merely to confuse the non-technical reader. The designs offered are more than theoretical — they are the result of actual construction and experiment. In many cases, the entire oscillation transformer has been rebuilt and rewound many times before satisfactory results were obtained.
