Construction of a Three-Electrode Vacuum Tube
Amateur radio manual providing comprehensive guidance on constructing a three-electrode vacuum tube, commonly known as an audion. The workshop manual covers the complete build sequence: bulb fabrication techniques, electrode assembly with tungsten filament preparation, grid winding procedures, and aluminum plate construction. Detailed instructions walk through the critical evacuation process using a mercury pump, the controlled heating procedures necessary for proper tube conditioning, and the final sealing method. Technical diagrams and assembly illustrations throughout make each step clear and reproducible. This construction guide serves as both a reference manual and practical workshop companion for anyone undertaking vacuum tube fabrication.
