General electronics projects. Reverse engineering of industrial electronics. Smaller projects that you can make at home or for school.
A talk about diodes of various sizes, from different ages, development in technology and power levels. The only things missing would be selenium diodes as I forgot where I put them and I do unfortunately not own a mercury arc rectifier.

A talk about various power vacuum, radio or electron tubes, depending on what you like to call them. Triodes, Tetrodes and Pentodes in a range from 10 to 800 Watt plate dissipation. PL36, EL34, 6P45S, PB2/200, PB2/250, QB3/300, 250TH, QB5/2000, TG1-2,5/4 and TG1-700/25 2x 30W EL34 Amplifier: https://kaizerpowerelectronics.dk/audio/2x30w-el34-tube-amplifier/ 1x 50W 6P45S Amplifier: https://kaizerpowerelectronics.dk/audio/100w-6p45s-monoblock-tube-amplifier/

A walk-through of different types of power capacitors that can be used in induction heater applications, ceramic, MICA, various types of film capacitors and extremely large internally water cooled power capacitors are demonstrated. 2 years back I bought a large lot of induction heater capacitors. Buy a 815 KVAr capacitor by contacting me here: https://highvoltageforum.net/index.php?topic=56.0

From all the different teardowns I have done through the time, I have always kept the nicest parts and pieces to use in future projects. These parts are after all free to start with and something like a heat sink is often very expensive from new once you get above the standard sizes for TO-247

MKP Power Film Capacitors plays a vital role in almost all power electronics applications. Either as filter, spike suppression or resonant energy storage. 3 years back I bought a large lot of MKP Power Film Capacitors. These will be used in a very large DRSSTC along with the IGBTs from day 3 video and film
