This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced. Only a few types are still used today, mainly in high-power, high-frequency applications. (Wikipedia).
Vacuum Tubes: Episode 1 - The Basics and the Diode
In this episode we finally dig into vacuum tubes. I cover what vacuum tubes are and the fundamentals behind their operation and then demonstrate two different diode type tubes.

Vacuum Tube Computer P.08.1 – OpAmp Clock: Inverter Upgrades
This episode is so epic, I’ve split it into two parts! In this first part, we take a look at our basic inverter design and see if we can’t improve it some. Then, once we’ve got a design we’re happy with, we do some massive testing on a bunch of different tubes to see how they each perform

Vacuum Tubes: Episode 3 – The Triode (Part 2)
In this episode we take a look at what’s going on inside the triode and why we weren’t seeing B+ voltage on our output. We do a bit of theory, a little reading, some simulation, and then finally some testing. There was so much to cover that I missed a bunch of stuff, I’ll be making a “Part

Arduino Based Low Voltage Vacuum Tube Tester
In this episode we take a stab at building a vacuum tube tester that gives us some proper, usable data! Granted, it’s all at super low voltages, just 24V in this case, but that actually works out perfectly for the types of circuits that we commonly build. Most importantly though, this was
