DIY Tube Tester. Adding more features to make this tube tester more useful. Part 5
Published at : 23 Dec 2025
Having managed to get the basic tube tester working, it is now time to add more features to it to make it truly useful. Leakage testing, gassy tube detection, higher resolution current measurement, and other small add-ons were obviously required. The one function that I really find useful is the tube selection method. Rather than using the common 'one switch per pin' method for re-directing the signals to the respective tube pins, I decided to try a 'plug and socket' system, which I am really happy with. Hope you agree. Enjoy the video.
