In the niche world of high-voltage engineering, Tesla coil design, and pulsed power electronics, few resources are as revered—or as difficult to navigate—as the Pupman Mailing List . For over two decades, the Pupman list has served as the digital water cooler for the world’s most brilliant (and often eccentric) minds in coil building, spark gaps, solid-state drives, and RF behavior.

Whether you are a hobbyist trying to resurrect a 4-foot spark gap coil, a historian documenting early internet engineering communities, or a patent researcher seeking prior art, seek out the cleanest, most authentic copy of 262txt you can find. Then open it in a simple text editor, start grepping, and uncover a lost decade of high-voltage genius.
