A superconducting diode bridge composed of four superconducting diodes efficiently converts AC to DC at cryogenic temperatures, achieving rectification efficiencies up to 42% ± 5%.

Crazy Tube Circuits has just dropped one of the hottest overdrive pedals of the year. It’s called Venus. It made its public debut at NAMM 2025.It was inspired by the iconic BK Butler Tube Driver ...

Given appropriate models for vacuum tubes, circuit simulators such as SPICE make analysis based on ... a 3/2-power relationship between plate current and plate-to-cathode voltage in a vacuum diode.

After a long experience with digital circuits, I wanted to build a 4-bit counter using only tubes and display the counter values on a Nixie tube. The knowledge about digital circuits based on tubes is ...

Design analysis of the K2-W Vacuum Tube Op Amp’s design and operation reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing.

The Significance of Diodes in Electronic Circuits. This inherent characteristic of diodes, to act as one-way gates, is pivotal in electronic circuits. When integrated into a circuit, a diode ensures ...

This point is charted on a graph (8:29). A diode tube is used to apply direct current in radio installations (8:43). An alternator is attached to the plate in the cathode of the diode tube (8:50) ...
